Crystal structure and theoretical studies of two π-conjugated fused-ring chalcones: (E)-1-(anthra­cen-9-yl)-3-(9-ethyl-9H-carbazol-3-yl)prop-2-en-1-one and (E)-1-(anthracen-9-yl)-3-[4-(9H-carbazol-9-yl)phen­yl]prop-2-en-1-one

Two chalcones were synthesized in Claisen–Schmidt condensation reactions. In the crystals, π–π inter­actions and weak C—H⋯O and C—H⋯π inter­actions are observed. The effect of these inter­molecular inter­actions in the solid state can be seen inthe difference between the experimental and theoretical optimized geometrical parameters.

Abstract

The title chalcones, C₃₁H₂₃NO and C₃₅H₂₃NO, were synthesized via Claisen–Schmidt condensation reactions. Both structures were solved and refined using single-crystal X-ray diffraction data and optimized at the ground state using the density functional theory (DFT) method with the B3LYP/6-311++G(d,p) level. In the crystals, π–π inter­ations and weak C—H⋯O and C—H⋯π inter­actions are observed. The effect of these inter­molecular inter­actions in the solid state can be seen by the difference between the experimental and theoretical optimized geometrical parameters. The structures have also been characterized by UV–Vis spectroscopy. The smallest energy gaps of 2.86 and 2.96 eV enhance the nonlinear responses of such mol­ecular systems. Hirshfeld surface analyses and 2D (two-dimensional) fingerprint plots were used to qu­antify the inter­molecular inter­actions present in the crystal, indicating that these are the most important contribution to the crystal packing.

Chemical context  

Chalcones satisfy the criteria of three features essential for high nonlinear activity in an organic compound, which are: a strong electron donor, a highly polarizable π-conjugated bridge and a strong π-electron acceptor. A chalcone mol­ecule with a π-conjugated system provides a large charge-transfer axis with appropriate substituent groups on the terminal aromatic rings. Polyaromatic hydro­carbons or π-conjugated materials such as anthracenyl chalcone provide the significant property for conductivity that led to tremendous advances in the field of organic electronics (Li et al., 2016 ▸). These conjugated materials modifications on the anthracenyl chalcone decrease the HOMO–LUMO energy gap (HOMO is the highest occupied molecular orbital and LUMO is the lowest unoccupied mol­ecular orbital), enhancing the nonlinear responses of such mol­ecular systems. In this work, we report the synthesis and combined experimental and theoretical studies of the anthracene chalcones (E)-1-(anthracen-9-yl)-3-(9-ethyl-9H-carbazol-3-yl)prop-2-en-1-one, I, and (E)-1-(anthracen-9-yl)-3-[4-(9H-carbazol-9-yl)phen­yl]prop-2-en-1-one, II. Additionally, the UV–vis absorption and Hirshfeld surface analyses are discussed.

Structural commentary  

The mol­ecular structures and optimized geometries of compounds I and II are shown in Fig. 1 ▸. The optimization of the mol­ecular geometries leading to energy minima was achieved using DFT with a 6-311++G(d,p) basis set, as implemented in the GAUSSIAN09 program package (Frisch et al., 2009 ▸). The calculated geometric parameters, such as bond lengths, bond angles and torsion angles, compared to the experimental data are presented in Table S1 in the supporting information and exhibit normal ranges. The theoretical bond lengths, bond angles and torsion angles correlate well with the experimental data.

Both I and II comprise a chalcone with an anthracene ring with 9-ethyl-9H-carbazole and 9-phenyl-9H-carbazole substituents, respectively. The asymmetric unit of II contains two crystallographically independent mol­ecules, A and B (Fig. 1 ▸ a). The C—C distances in the central ring of the anthracene units show a little variations compared to the other rings (C2—C3, C4—C5, C9—C10 and C11—C12), which are much shorter. These observations are consistent with an electronic structure for the anthracene units where a central ring displaying aromatic delocalization is flanked by two isolated diene units (Glidewell & Lloyd, 1984 ▸).

Both theoretical and experimental structures (Fig. 1 ▸) exist in an s-trans configuration with respect to the enone moiety, with bond lengths C15=O1 [Exp = 1.220 (2) Å and DFT = 1.22 Å in I; Exp = 1.213 (3) (A) and 1.218 (3) Å (B), and DFT = 1.22 Å in II] and C16=C17 [Exp = 1.329 (2) Å and DFT = 1.35 Å in I; Exp = 1.319 (3) (A) and 1.320 (4) Å (B), and DFT = 1.35 Å in II]. Both I and II (A and B) are twisted at the C14—C15 bond, with C1—C14—C15—C16 torsion angles of −92.6 (2) (in I), 84.8 (3) (in IIA) and 106.3 (3)° (in IIB). The corresponding torsion angles for DFT are −85.84 and 85.63°, respectively. Additionally, in compound II, rings Y and Z (A) and rings Y′ and Z′ (B) are also twisted at the C21—N1 bond, with C20—C21—N1—C24 torsion angles of Exp = 64.1 (4)° (A) and 46.2 (4)° (B), and DFT = 55.03°. The large twist angles are due to the bulkiness of the strong electron-donor anthracene ring system and substituent ring system (Zainuri et al., 2018a ▸,b ▸,c ▸). Meanwhile, compounds I and II are found to be slightly twisted at the C17—C18 bond, with C16—C17—C18—C19 torsion angles of Exp = −16.4 (3)° and DFT = −1.38 for compound I, and Exp = −171.2 (3)° (A) and 11.4 (5)° (B), and DFT = −1.70° for compound II. The slight differences in the torsion angles between the experimental and DFT results in both compounds are due to the formation of inter­molecular C—H⋯O and C—H⋯π inter­actions involving all the fused-ring systems, which are not taken into consideration during the optimization process (Arshad et al., 2018 ▸).

The enone moiety in I [O1/C15–C17, maximum deviation = 0.0308 (19) Å at atom C16] makes dihedral angles of 86.93 (19) and 21.21 (19)° with the anthracene ring [maximum deviation = 0.0117 (19) Å at C9] and ring X [maximum deviation = 0.0363 (18) Å at C29], respectively. In compound II, the enone moiety [O1/C15–C17, maximum deviation = 0.017 (3) Å at C15A] for mol­ecule A forms dihedral angles of 84.76 (17), 87.61 (17) and 72.35 (17)° with the anthracene ring [maximum deviation = 0.029 (3) Å at C14A], ring Y [maximum deviation = 0.008 (3) Å at C19A] and ring Z [maximum deviation = 0.043 (3) Å at C34A], respectively. The anthracene ring forms dihedral angles of 89.63 (11) and 62.11 (7)° with rings Y and Z, respectively, and the dihedral angle between rings Y and Z is 61.73 (10)°. In addition, for mol­ecule B, the enone moiety [O1/C15–C17, maximum deviation = 0.036 (3) Å at C16B] forms dihedral angles of 72.2 (3), 13.5 (3) and 87.2 (3)° with the anthracene ring [maximum deviation = 0.018 (4) Å at C10B], ring Y′ [maximum deviation = 0.010 (3) Å at C20B] and ring Z′ [maximum deviation = 1.441 (2) Å at N1B], respectively. The anthracene ring forms dihedral angles of 61.46 (11) and 54.80 (7)° with rings Y′ and Z′, respectively, and the dihedral angle between rings Y′ and Z′ is 48.92 (11)°.

Supra­molecular features  

The crystal packing of I shows weak π–π inter­actions (Fig. 2 ▸ a) involving Cg1⋯Cg5 = 3.7267 (11) Å (symmetry code: 1 − x, 1 − y, 1 − z), Cg2⋯Cg4 = 3.6669 (12) Å (symmetry code: 2 − x, 2 − y, 1 − z), Cg3⋯Cg3 = 3.6585 (11) Å (symmetry code: 2 − x, 2 − y, 1 − z) and Cg4⋯Cg4 = 3.6790 (12) Å (symmetry code: 1 − x, 2 − y, 1 − z), where Cg1, Cg2, Cg3, Cg4 and Cg5 are the centroids of rings N1/C20/C21/C26/C27, C1–C6, C1/C6–C8/C13/C14, C8–C13, C18–C20/C27-C29, respectively. The packing is further linked into an infinite three-dimensional supra­molecular network.

Lists of weak hydrogen-bond inter­molecular inter­actions are shown in Table 1 ▸. The crystal packing of II (Fig. 1 ▸ b) shows weak C12B—H12B⋯O1 inter­molecular hydrogen bonds connecting the mol­ecules into an infinite one-dimensional chain along the c axis. In addition, weak inter­molecular C5B—H5BA⋯Cg6, C27B—H27B⋯Cg7, C28B—H28B⋯Cg8, C11A—H11A⋯Cg9 and C7B—H7B⋯Cg10 inter­actions are also observed in the crystal packing and further stabilize the crystal structure, where Cg6, Cg7, Cg8, Cg9 and Cg10 are the centroids of rings N1A/C24A/C29A/C30A/C35A, C1A–C6A, C1A/C6A–C8A/C13A/C14A, C18A–C23A and C24A–C29A, respectively. These weak inter­molecular C—H⋯O and C—H⋯π inter­actions bridge the mol­ecules into an infinite one-dimensional column along the c axis.

UV–Vis absorption analysis  

The electronic absorption spectra of I and II have been calculated using time-dependent DFT at the B3LYP/6-311++G(d,p) level in the gas phase and give values of 396 (I) and 383 nm (II). The absorption characteristics of I and II are observed in the UV region at 393 and 388 nm, as shown in Fig. 3 ▸. The theoretical wavelengths are shifted to higher values and are due to the fact that the calculations are confined to the gaseous medium, whereas the observations are from the solution state, using DMSO as solvent (Zainuri et al., 2017 ▸).

Figure 3.

The UV–Vis absorption spectra of compounds I and II.

According to an investigation on the frontier mol­ecular orbital (FMO) energy levels of the title compounds, the corresponding electronic transfer are found to happen between the HOMO and LUMO orbitals, as shown in Fig. 4 ▸. The positive phase is red and the negative is green. In Fig. 4 ▸, the charge densities in the ground state (HOMO) are mainly delocalized over the anthracenyl donor ring, while in the excited state (LUMO), the charge densities were accumulated on the π-conjugated enone bridge and the terminal electron acceptor group. The values of the energy separations between the HOMO and LUMO are 2.98 and 3.12 eV for compounds I and II, respectively. Through an extrapolation of the linear trend observed in the optical spectra, the experimental energy band gaps in I and II are 2.86 and 2.96 eV, respectively. These optical band-gap values indicate the suitability of this compound for optoelectronic applications, as was also reported previously for a chalcone structure by Tejkiran et al. (2016 ▸). In addition, Konkol et al. (2016 ▸) studied the structural and optical properties of fused rings where the results showed that fused rings have a lower energy band gap.

Hirshfeld surface (HS) analysis  

The program CrystalExplorer (Wolff et al., 2012 ▸) was used to analyse the inter­actions in the crystal. Fig. 5 ▸(a) show the HS mapped over d _norm, where the red spots indicate the regions of donor–acceptor inter­actions. The C—H⋯O contacts are only present in compound II. In addition, the presence of C—H⋯π inter­actions only occurs in compound II, indicated through a combination of pale-orange bright-red spots which are present on the HS mapped over shape index surface, identified with black arrows (Fig. 5 ▸ b). The large flat region delineated by a blue outline refers to the π–π stacking inter­actions. The curved nature of the compound reveals that π–π stacking inter­actions are present in compound I. Meanwhile, these inter­actions are absent in compound II.

Figure 5.

View of the Hirshfeld surfaces for the title compounds, showing (a) d _norm with the red spots showing the involvement of the C—H⋯O inter­actions in II, (b) mapped over d _e with the pale-orange spots within the black arrows indicating the C—H⋯π inter­actions in II and (c) mapped over curvedness with the black arrows indicating the π–π inter­actions in I.

The fingerprint plot shown in Fig. 6 ▸ indicates the H⋯H, H⋯O, C⋯H and C⋯C inter­actions with their relative percentage contributions. The H⋯H contacts have the largest overall contribution to the HS, and these inter­actions dominate in the crystal structure. The contribution from H⋯O/O⋯H contacts to the HS showing two narrow spikes provides evidence for the presence of inter­molecular C—H⋯O inter­actions in Fig. 6 ▸ for compound II. Meanwhile, there is no spike in the fingerprint of compound I. The 7.5% O⋯H contribution shown in compound I is the average percentage interaction from the total interactions presence in I. In compound I, there are no interactions other than the π–π interactions, which makes the percentage of the O⋯H contribution is slightly higher. Hence, a discussion on the percentage difference between I. and II. is invalid. The significant C—H⋯π inter­actions for compound II are indicated by the wings d _e + d _i ∼ 2.6 Å.

Database survey  

A survey of the Cambridge Structural Database (CSD, Version 5.39, last update November 2017; Groom et al., 2016 ▸) revealed several fused-ring-substituted chalcones similar to I and II. There are four compounds which have an anthrancene ketone subtituent on the chalcone, including 9-anthryl styryl ketone and 9,10-anthryl bis­(styryl ketone) reported by Harlow et al. (1975 ▸). (2E)-1-(Anthracen-9-yl)-3-[4-(propan-2-yl)phen­yl]prop-2-en-1-one was reported by Girisha et al. (2016 ▸), while (E)-1-(anthracen-9-yl)-3-(2-chloro-6-fluoro­phen­yl)prop-2-en-1-one was reported by Abdullah et al. (2016 ▸). Zainuri et al. (2018a ▸) reported both anthrancene substituents on chalcone (E)-1,3-bis­(anthracen-9-yl)prop-2-en-1-one. Other related compounds include 1-(anthracen-9-yl)-2-methyl­prop-2-en-1-one (Agrahari et al., 2015 ▸), 9-anthroylacetone (Cicogna et al., 2004 ▸), (E)-1-(anthracen-9-yl)-3-[4-(piperidin-1-yl)phen­yl]prop-2-en-1-one and (E)-1-(anthracen-9-yl)-3-[4-(di­phenyl­amino)­phen­yl]prop-2-en-1-one (Zainuri et al., 2018b ▸,c ▸).

Synthesis and crystallization  

A mixture of 9-acetyl­anthrancene (0.5 mmol) and 9-ethylcarbazole-3-carbaldehyde (0.5 mmol) and 4-(9H-carbazol-9-yl)benzaldehyde (0.5 mmol) for compounds I and II, respectively, was dissolved in methanol (20 ml). A catalytic amount of NaOH (5 ml, 20%) was added to the solution dropwise under vigorous stirring. The reaction mixture was stirred for about 5–6 h at room temperature. After stirring, the contents of the flask were poured into ice-cold water (50 ml). The resultant crude products were filtered, washed successively with distilled water and recrystallized from acetone to give the corresponding chalcones (Scheme 1). Single crystals of I and II suitable for X-ray diffraction were obtained by slow evaporation from acetone solutions.

Refinement  

Crystal data collection and structure refinement details are summarized in Table 2 ▸. All H atoms were positioned geometrically (C—H = 0.93, 0.96 and 0.97 Å in I, and 0.93 Å in II) and refined using a riding model, with U _iso(H) = 1.2 or 1.5U _eq(C). A rotating group model was applied to the methyl group in I.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
