Synthesis and Characterization of Photoswitchable Dithienylethene‐Based Chiral Bisoxazoline Compounds with Bidirectional Visible‐Light Control

Abstract

In this paper, we have successfully synthesized dithienylethene‐based chiral bisoxazoline ligands with bidirectional photoswitching capabilities under visible light irradiation and proposed a strategy for adjusting the conjugation system length in sensitizer groups. The detailed experimental procedures and the characterization data are presented in the main text and the Supporting Information. Despite their moderate photoswitching rates, these ligands provide a promising approach towards developing fully visible light‐responsive chiral catalysts.
