N ²-(7-Bromo-9-butyl-9H-carbazol-2-yl)-9,9-diethyl-N ²,N ⁷,N ⁷-triphenyl-9H-fluorene-2,7-diamine

Abstract

In the title mol­ecule, C₅₁H₄₆BrN₃, the central fluorene residue is planar (r.m.s. deviation = 0.0203 Å), as is the carbazole system (r.m.s. deviation = 0.0154 Å), and these groups are almost orthogonal [dihedral angle = 79.72 (3)°]. The three-dimensional architecture is consolidated by C—H⋯π inter­actions. The butyl substituent is disordered with two sites resolved for the terminal propyl atoms; the major component had a site-occupancy factor of 0.686 (3).

Comment

Carbazole (Thomas et al., 2001; Thomas et al., 2004) and fluorene (Baheti et al., 2009; Baheti et al., 2011) derivatives have been widely used as hole-transporting and emitting materials in organic light-emitting diodes and as sensitizers in dye-sensitized solar cells. The title compound, N²-(7-bromo-9-butyl-9H-carbazol-2-yl)-9,9-diethyl-N²,N⁷,N⁷-triphenyl-9H-fluorene-2,7-diamine (I), was synthesized as an intermediate in the synthetic sequence for the development of donor-acceptor compounds suitable for application as sensitizers in dye-sensitized solar cells.. Herein, the crystal structure determination of (I) is described. Related structures are known, i.e. 9,9-diethyl-N²,N²,N⁷,N⁷-tetraphenyl-9H-fluorene-2,7-diamine (Low et al., 2005), 9-butyl-9H-carbazole (Chen et al., 2009) and 2,7-dibromo-9-octyl-9H-carbazole (Gagnon & Laliberté, 2008).

In (I), Fig. 1, the 13 non-hydrogen atoms of the central fluorene residue are co-planar (r.m.s. deviation = 0.0203 Å). Similarly, the 13 non-hydrogen atoms of the carbazole system forms a plane (r.m.s. deviation = 0.0154 Å). The dihedral angle between the fluorene and carbazole fused ring systems is 79.72 (3)°, indicating an almost orthogonal relationship. The fluorene system forms dihedral angles of 88.22 (6) and 58.51 (7)° with the C1–C6 and C7–C12 N1-amine-phenyl rings, respectively; the dihedral angle between these phenyl rings is 64.45 (8) °. At the N2-amine side of the molecule, the dihedral angles formed between the fluorene and carbazole fused ring systems with the N2-bound phenyl ring are 62.96 (6) and 71.53 (6)°, respectively. With respect to the five-membered ring in the fluorene residue, the ethyl substituents are virtually perpendicular as seen in the values of the C17–C25–C26–C27 and C17–C25–C28–C29 torsion angles of 54.4 (3) and -60.6 (3)°, respectively. Finally, the major component of the disordered n-butyl chain adopts an extended trans conformation with the C48–C49–C50–C51 torsion angle being 173.2 (3)°; the equivalent value for the minor component is 179.8 (8)°.

Molecules are consolidated in the three-dimensional architecture by C—H···π interactions, Fig. 2 and Table 1.

Experimental

A mixture of 9,9-diethyl-N²,N²,N⁷-triphenyl-9H-fluorene-2,7-diamine, 2,7-dibromo-9-butyl-9H-carbazole, bis(diphenylphosphino)ferrocene, sodium tert-butoxide, and toluene (20 ml) was heated at 353 K for 36 h. The resultant solution was poured into water and extracted with dichloromethane. After drying over anhydrous sodium sulfate the combined dichloromethane extract was evaporated to yield a crude product. It was purified by column chromatography on silica gel using 4:1 mixture of hexanes and dichloromethane. White solid. Yield 66%; M.pt. 413–415 K. Re-crystallization was by slow evaporation of a solution of (I) from a 1:1 mixture of hexanes and dichloromethane. ¹H NMR (500 MHz, CDCl₃) δ 0.39 (t, J = 7.5 Hz, 6 H), 0.85–0.88 (m, 3 H), 1.29 (dd, J = 15.5 Hz, 7.5 Hz, 2 H), 1.71 (t, J = 7.5 Hz, 2 H), 1.81 (dd, J = 14.5 Hz, 7.5 Hz, 4 H), 4.06 (t, J = 7.0 Hz, 2 H), 6.98 (m, 5 H), 7.07–7.14 (m, 8 H), 7.17 (d, J = 8.5 Hz, 2 H), 7.23–7.25 (m, 3 H), 7.26–7.30 (m, 4 H), 7.46 (d, J = 1.0 Hz, 1 H), 7.49–7.52 (m, 2 H), 7.82 (d, J = 8.5 Hz, 1 H), 7.87 (d, J = 8.5 Hz, 1 H); ¹³C NMR (125.77 MHz, CDCl₃) δ 151.32, 151.25, 148.45, 148.11, 147.02, 146.82, 146.58, 141.76, 141.71, 136.69, 136.66, 129.16, 123.87, 122.38, 122.06, 121.98, 120.83, 120.76, 119.80, 119.58, 119.45, 118.27, 117.74, 116.91, 111.58, 104.15, 56.09, 42.82, 32.59, 30.95, 20.45, 13.81, 8.63. HRMS calcd. for C₅₁H₄₆BrN₃ [M + H] m/z 780.2948 found 780.2945.

Refinement

Carbon-bound H-atoms were placed in calculated positions [C—H 0.95 to 0.99 Å, U_iso(H) 1.2 to 1.5U_eq(C)] and were included in the refinement in the riding model approximation. The terminal propyl group of the butyl substituent was found to be disordered. Two sites were resolved and from fractional refinement (common anisotropic displacement parameters for pairs of atoms, and with 1,2- and 1,3- C—C distance constraints = 1.50±0.01 and 2.35±0.01 Å, respectively). The major component had a site occupancy factor = 0.686 (3).

Special details

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

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
