Abstract

By integrating N, N-dimethyl (donor, D) and fumaronitrile (acceptor, A) groups with the biphenyl fluorogen, which has an aggregation-induced emission (AIE) property, we have obtained the target molecule 2-(4-bromophenyl)-3-(4′-(dimethylamino)-biphenyl-4-yl) fumaronitrile (BDABFN). BDABFN is a red-to-near-infrared-emitting fluorogen with emission peaks at 653 and 710 nm for its amorphous and crystal solids, respectively. BDABFN ...
