Shedding light on porous materials

A light-responsive crystalline material the porosity of which changes when light shines on it has been developed by researchers at Kyoto University’s Institute for Integrated Cell-Material Sciences (iCeMS) and the University of Tokyo, Japan. Such materials might find applications in the development of photoresponsive materials controlled-release drug-delivery systems in dynamic tissue engineering scaffolds and other areas. The current system is based on a flexible porous crystal composed of a photoresponsive dithienylethene derivative, zinc ions, and 1,4-benenzenedicarboxylate which together form a porous coordination polymer.
