| Abstract: | 9‐Fluorenylidenemalononitrile (FDCN) or 1, 1‐diphenyl‐2,2‐dicyanoethylene (DPCN) reacted with 10‐methyl‐9,10‐dihydroacridine (AcrH2) under irradiation (λ 320 nm) to give couping products. In order to gain further insight into the mechanism of the photo‐induced reaction, the photophysics of the reactions of FDCN or DPCN with AcrH2 have been investigated by using UV‐vis spectroscopy, fluorescence spectroscopy, excitation spectroscopy and time‐resolved fluorescence spectroscopy, respectively. The results show that FDCN or DPCN interacts with AcrH2 in the ground states to form a charge transfer complex, which further reacts to give the coupling product upon. irradiation. |
