The synthesis, single crystal X-ray structures, spectroscopic properties and molecular mechanics calculations of three systematically substituted 3,5-diaryl-1H-pyrrole-2-carboxylic acid ethyl esters 1a–c are described. The goal is to develop design principles for the generation of new class of fluorescent switches constructed from an aryl-heteroaryl architecture containing a virtual (C0) spacer. The
描述了三种系统取代的3,5-二芳基-1 H-吡咯-2-羧酸乙酯1a–c的合成,单晶X射线结构,光谱性质和分子力学计算。目标是开发设计原理,以生成由包含虚拟(C 0)间隔基的芳基-杂芳基结构构成的新型荧光开关。的光谱效应电子给体 1b的对-二甲氨基取代基以及合并的空间和电子给体研究了化合物1c的o-甲基-对-二甲基氨基的影响,以确定所需的结构基序,以实现传感器亚基的正交预取向。
