Correction: Sterically controlled 5-exo-dig cyclization enables synthesis of non-benzenoid polycyclic aromatic hydrocarbons with intriguing (anti)aromaticity and diradical properties

Abstract

Correction for ‘Sterically controlled 5-exo-dig cyclization enables synthesis of non-benzenoid polycyclic aromatic hydrocarbons with intriguing (anti)aromaticity and diradical properties’ by Liangliang Chen et al., Chem. Sci., 2026, https://doi.org/10.1039/d6sc00121a.

The authors regret that due to an error in figure assembly part of Fig. 2b was obscured in the final version of the manuscript. The corrected Fig. 2 is shown below. This does not alter the interpretations or conclusions of the paper.

Fig. 1. The calculated NICS(1)_zz values at 1 Å of Z axis of (a) 1, (b) 2 and (c) 3. The calculated ACID plots of (d) 1, (e) 2 and (f) 3. The clockwise ring current represents aromaticity and the counter-clockwise ring current represents antiaromaticity. (g) The UV-vis absorption spectra of 1, 2 and 3 (10⁻⁵ mol L⁻¹ in DCM solution). (h) Cyclic voltammograms (CV) curves of 1, 2 and 3. The calculated absorption transitions of (i) 1, (j) 2 and (k) 3 based on TD-DFT calculations. (i) and (k) were based on M06-2X/6-311G(d,p) level of theory with closed-shell single state. (j) was based on UM06-2X/6-311G(d,p) level of theory with open-shell singlet state.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
