Thioindigo photoswitches available for the modulation of hydrogels’ stiffness by visible light

Abstract

Chromophore molecules that undergo reversible isomerization under excitation by two different wavelengths of light are commonly referred to as photoswitchable molecules. Through the use of light-induced reversible changes combined with precisely spatial and temporal light control, photoswitchable molecules can be applied in areas such as actuators, optics, molecular motors, and photobiology.
