Diarylethenes (DAEs) have recently attracted great attention for their applications in light-responsive materials. As much efforts have been directed towards the elucidation of the structure-property relationship of DAE derivatives, improving photochromic performances through structure optimization is still worthy of study. Herein, three isomeric diarylethenes with thienopyridine units are designed for gaining insights into substituent position effect on photochromic performances. It is shown that the nitrogen atom in pyridine rings shows influence on the photochromic behaviors, such as photoreaction quantum yields, conversion ratios of target systems. Distinctively, thieno [3,2-b]pyridine-containing I (TP3) displays a novel solvent-dependent photochromic activity. And the photochromic reactivity of thieno [2,3-b]pyridine-containing II (TP1) can be specifically blocked by Cu2+, showing the gated photochromism. The diverse photochromic properties make the target systems promising candidates for the development of practical mol. devices with certain functions.
