Abstract

We have developed a series of 2-monoaryl-5-diarylmethylene analogs of the green fluorescent protein chromophore to study their viscosity-induced emission (VIE) properties. The analogs were synthesized by a condensation with methyl imidate and N-(diarylmethylene)glycinate. Among the analogs, the N-methylpyrrol-2-yl-substituted analog 1h induced the most remarkable VIE behavior in triglyceride and lipid bilayers probably due to the high π-electron-rich property of the pyrrole ring. The pyrrole substituent in imidazolone analogs can be expected to become a common template for introducing VIE behavior.

通过在 2-位连接 N-甲基吡咯扩展共轭的 5-(二亚甲基)咪唑啉酮的粘度诱导发射

我们开发了一系列绿色荧光蛋白发色团的 2-单芳基-5-二亚甲基类似物，以研究它们的粘度诱导发射（VIE）特性。这些类似物是通过亚胺酸甲酯和 N-（二芳基亚甲基）甘氨酸缩合合成的。在这些类似物中，N-甲基吡咯-2-基取代的类似物 1h 在甘油三酯和脂质双分子层中具有最显著的 VIE 特性，这可能是由于吡咯环具有高π电子富集特性。咪唑啉酮类似物中的吡咯取代基有望成为引入 VIE 行为的常见模板。
