yellowish-green emission, and the emission maximum wavelength is from 534 nm to 547 nm. In particular, the obtained luminophores have large Stokes shifts (>100 nm) and the emission intensity in the solid state is stronger than that in solution with aggregation-induced emission enhancement (AIEE). In addition, the amino-aryl-maleimide luminophores respond to the increasing polarity of various solvents
带有共轭单元的马来酰亚胺基发光体作为有机发光体,由于其优异的发光性能和广泛的应用而引起了广泛的科学兴趣。在本文中,我们通过合成氨基马来酰亚胺衍生物后通过一条简单的路线,通过 Suzuki-Miyaura 偶联合成了一系列氨基-芳基-马来酰亚胺发光体。所得发光体呈黄绿色发射,发射最大波长为534~547nm。特别是,获得的发光体具有较大的斯托克斯位移(>100 nm),并且固态发射强度强于具有聚集诱导发射增强(AIEE)的溶液。此外,氨基-芳基-马来酰亚胺发光团对各种溶剂的极性增加做出响应,并显示出正的溶剂致变色荧光。
