摘要:
A series of fused carbazole-based luminophores with donor-acceptor structures were synthesized (DCB-H, DCB-Br and TCB-H). The photophysical, electrochemical properties, crystal packing structures were investigated in detail. The restriction of intermolecular rotation of benzophenone units lead to typical aggregation-induced emission properties, giving potential to be used as fluorescence sensors for explosives, such as 2, 4, 6-trinitrophenol.
