Dithienylethenes (DTEs) are a rare class of small molecules, which are capable of undergoing photochemical electrocyclization that is rapid, reversible, and most importantly—thermally forbidden. This makes them the ideal scaffold for building catalysts that can be activated and deactivated on demand with short pulses of light of the appropriate wavelength. In the following Perspective, we review the strategies toward achieving photoswitchable control with DTE metal-chelating and organocatalytic ligands, compare their effectiveness with a “dynamic range” metric that we introduce, and highlight the various development milestones. Lastly, we outline potential avenues for further growth of this relatively young field of molecular catalysis.

基于二噻吩基乙烯的光开关催化剂:最新进展和未来展望

二噻吩基乙烯(DTE)是一类罕见的小分子,能够进行光化学电环化反应,该反应是快速,可逆的,最重要的是禁止加热。这使它们成为构建催化剂的理想支架,该催化剂可以根据需要用适当波长的短脉冲光进行活化和失活。在下面的“观点”中,我们回顾了使用DTE金属螯合和有机催化配体实现光开关控制的策略,将其有效性与我们介绍的“动态范围”指标进行了比较,并重点介绍了各种发展里程碑。最后,我们概述了这个相对年轻的分子催化领域进一步发展的潜在途径。
