Aggregation‐induced emission (AIE)‐active maleimide dyes, namely, 2‐p‐toluidino‐N‐p‐tolylmaleimide, 3‐phenyl‐2‐toluidino‐N‐p‐tolylmaleimide, 2‐p‐thiocresyl‐3‐p‐toluidino‐N‐p‐tolylmaleimide, and 2,3‐dithiocresyl‐N‐arylmaleimides, were synthesized by facile synthetic procedures. The dyes show intense emission in the solid state, and emission colors were controlled from green (λmax=527 nm) to orange (λmax=609 nm)
聚集诱导发光(AIE)-active马来酰亚胺染料,即,2- p -toluidino- ñ - p -tolylmaleimide,3-苯基-2- toluidino- Ñ - p -tolylmaleimide,2- p -thiocresyl -3- p - toluidino- ñ - p -tolylmaleimide和2,3- dithiocresyl- ñ -arylmaleimides,通过简便的合成方法合成。染料显示出在固体状态下强发射,以及发光颜色从绿色控制(λ最大= 527纳米)到橙色(λ最大通过改变马来酰亚胺的2位和3位上的取代基以及固态堆积结构来改变= 609 nm)。2,3-二取代的马来酰亚胺染料有效地经历了其发射波长的红移。此外,一些染料表现出机械变色和多态性,并且它们的发射性质显着取决于固体样品的形态。通过X射线衍射研究了发射行为的机理。马来酰亚胺环上氮原子
