Adjusting Emission Behaviors of Molecules Based Benzothiadiazole by Intermolecular Interaction and Mechano-responsive
摘要
Abstract
It is a feasible way to adjust emission behaviors by molecular conformation and intermolecular interac-tions.Herein,two multifunctional materials,4,4'-(benzo[c][1,2,5]thiadiazole-4,7-diyl)bis(N,N-diphenylani-line)and 4-(7-(9,9-dimethylacridin-10(9H)-yl)benzo[c][1,2,5]thiadiazol-4-yl)-N,N-diphenylaniline,namely TBT and DBT,with donor-acceptor-donor(D-A-D)and D-A-D'structures composed of 2,1,3-benzothiadiazole(BT)acceptor and the different donors of triphenylamine(TPA)and 9,9-dimethyl-9,10-dihydroacridine(DMAC)were synthesized.These materials exhibit not only polymorphism-dependent emission but also multicolor lumines-cence switch in response to the external stimulus.The high-contrast crystal-dependent emission behaviors of TBT(TBT-O:λPL=593 nm and TBT-R:λPL=616 nm)and DBT(DBT-Y:λPL=570 nm,DBT-O:λPL=605 nm and DBT-R:λPL=642 nm)were observed.TBT with double TPA groups exhibits four reversible color switches,while DBT with TPA and DMAC groups shows irreversible bicolor change.关键词
