A simple microwave assisted protocol for the construction of maleimides from various anilines and dialkyl acetylene dicarboxylates has been demonstrated. The AIE property of one of the maleimide derivatives has been studied in detail. The maleimide is AIE-active, and its color, fluorescence efficiency, quantum yield and fluorescence lifetime can be readily tuned by adding water to the THF solution. Compound 3a is found to be weakly luminescent when it is dissolved in THF, but its luminescence intensity increases enormously by the gradual addition of water up to 90% with associated increase in quantum yield and fluorescence lifetime.
已经证明了一种简单的微波辅助方案,用于从各种苯胺和乙炔二羧酸二烷基酯构建马来酰亚胺。对一种马来酰亚胺衍生物的 AIE 特性进行了详细研究。马来酰亚胺具有 AIE 活性,其颜色、荧光效率、量子产率和荧光寿命可以通过向 THF 溶液中添加水来轻松调节。研究发现,化合物 3a 溶解在 THF 中时发光较弱,但随着水的逐渐添加至 90%,其发光强度大幅增加,同时量子产率和荧光寿命也相应增加。
