A novel “push–pull” diarylethene molecule consisting of an electron withdrawing ethene bridge (1,8-naphthalic anhydride) and two moderate electron donating side chains (2,5-dimethylthiophene) has been designed and synthesized. The photochromism study, together with density functional theory calculations, revealed that the molecule exhibits reversible fluorescence switching capacity upon photo-isomerization
设计并合成了一种新型的“推挽式”二芳基
乙烯分子,该分子由吸电子的
乙烯桥(1,8-
萘酐)和两个中等的供电子侧链(
2,5-二甲基噻吩)组成。光致变色研究以及密度泛函理论计算表明,该分子在光异构化后显示出可逆的荧光转换能力,并且由于分子内电荷转移而具有显着的溶剂致变色,其中荧光最大值发生了超过150 nm的红移。
