Pashazadeh, Ramin and Pander, Piotr and Bucinskas, Audrius and Skabara, Peter J. and Dias, Fernando B. and Grazulevicius, Juozas V. (2018) 'An iminodibenzyl–quinoxaline–iminodibenzyl scaffold as a mechanochromic and dual emitter : donor and bridge effects on optical properties.', Chemical communications., 54 (98). pp. 13857-13860.
The influence of phenyl linkage and donor strength on the photophysical properties of new derivatives of quinoxaline-containing iminodibenzyl and iminostilbene moieties is studied. The donor–acceptor derivatives showed dual thermally activated delayed fluorescence (TADF) and room temperature phosphorescence (RTP) despite a large energy gap between the excited singlet and triplet states (ca. 0.5 eV). This extremely rare observation is explained by the twisted and rigidified structure of the iminodibenzyl moiety.
