Synthesis and Spectroscopic Study of Naphthalimide Derivatives based on Aggregation Induction Properties

以分子内电荷转移为原理,选用萘酰亚胺为荧光团,与三苯胺通过偶联反应,制备了一种萘酰亚胺衍生物有机光功能小分子材料,其合成路线简单、实验操作条件易控、成品产率较高.对其光学性能进行研究,在不同溶剂中的光学性能主要表现出两个强吸收带,荧光发射达到近红外区域,其表现出了非常明显的聚集诱导发光(AIE)特性,固体表现出很强的橘橙色荧光现象.

Based on the principle of intramolecular charge transfer,naphthimide was selected as the fluorophore and reacted with triphenylamine through a coupling reaction to prepare a naphthalimide derivative organic optical functional small molecule material.The synthesis route is simple and the experimental operating conditions are easy to control,and the yield of target product is very high.Its optical properties were studied.Its optical properties were studied.The optical properties in different solvents mainly showed two strong absorption bands.Its fluorescence emission reached the near infrared region,and exhibited very obvious aggregation-induced emission(AIE)characteristics.The solid showed a strong orange fluorescence phenomenon.
