groups-comprising diarylethenes of 2,3-diarylcyclopent-2-en-1-one (DCP) series have been synthesized and its photochromic, fluorescent as well as acidochromic features have been investigated. It was shown that photochromic properties of the substances depend strong on their structures; the non-symmetry of the photochromic molecule is a powerful tool to properly control and tune the parameters of diarylethenes. It
合成了新的含2,3-二芳基环戊-2-en-1-one(DCP)系列二烷
氨基的二
芳烃,并研究了其光致变色,荧光和酸性变色特征。结果表明,这些物质的光致变色特性强烈依赖于其结构。光致变色分子的非对称性是正确控制和调整二
芳烃的参数的有力工具。已经发现合成的最有希望的DCP是在
乙烯“桥”中而不是芳基部分中含有二烷基
氨基的那些,因为它们具有光和pH可转换的发射以及热稳定性。已经确定,在苯
戊烯酮环的第二位置引入苯残基导致光致变色性质的消失。
