Chen, Qiao;Chen, Xinyu;Han, Yanning;Zhang, Tong;Li, Cheng-Peng;Mu, Jianshuai;Zhang, Jingbo;Hao, Jingjun;Xue, Pengchong research published 《 Multistimuli-Responsive Fluorescent Switches Based on Reversible Decomposition and Regeneration of charge-transfer Complexes》, the research content is summarized as follows. Charge transfer (CT) complexes of 4,4′-bis(9H-carbazol-9-yl)-1,1′-biphenyl (CBP) and three acceptors emitted cyan, green and orange fluorescence and lower LUMO energy levels of acceptors promoted longer emission wavelengths. Moreover, they could reversibly convert their luminescent colors under force and then fuming by chlorinated hydrocarbon solvents. Amazingly, acetonitrile vapor annealing might decompose CT complexes to form pure CBP crystalline phase, which induced sharp changes in fluorescence colors. As a result, a largest emission shift was more than 220 nm. CT complexes could also be formed through pressing the mixture of donor and acceptor and the emission color gradually changes from blue to cyan, green, white, yellow, orange and even red with extending grinding time, realizing the full color luminescence in the visible light region. Owing to their excellent stimuli-responsive behaviors, anticounterfeiting papers with two fluorescent colors have been constructed. Moreover, fluorescence colors of papers could be reversibly transformed under solvent annealing treatment. High-resolution patterns in both papers might be written by stylus printer and be erased by solvent fuming with high reversibility.
