A new photochromic diarylethene with a 2-(1H-dithienobenzoimidazole)phenol unit has been synthesized. The gated photochromism and fluorescence switching behaviors of the compound induced by acid/base were investigated. Addition of acid enhanced its fluorescence intensity and the remotely photochromic reactivity was activated. Moreover, the fluorescence intensity of the diarylethene was notably enhanced...
A new asymmetrical photochromic diarylethene with a 6-(hydroxymethyl)picolinohydrazide unit has been synthesized. Its multichromism behaviors induced by base/acid and light were investigated. The compound exhibited high selectivity and sensitivity toward Al3+, and the fluorescence intensity of the diarylethene was remarkably enhanced by 95-fold and the emission peak was blue-shifted from 585 nm to...
