Photoresponsive metal-organic framework materials for advance applications

Abstract

The interaction between light and material produces extensive phenomena within the molecular system that lead to the advance applications in the field of material science. In this regard, metal-organic framework (MOF) materials become the superior candidates among others because of their easy tailor-made synthetic methods via incorporation of photoactive moiety in the structural assembly. The photoresponsive MOFs exhibit a massive variety of exciting properties, including photochromism, photomagnetism, photoluminescence, photon up or down conversion, photoconductivity, nonlinear optical property, photosalient effect and photoinduced switching of conformations. These photoresponsive properties of MOFs regulate different potential applications, such as on-demand gas sorption and separation, optical sensing, fabrication of photoactuator and photosensing electronic devices, dye degradation, catalysis, cargo delivery, ink-free erasable printing, bio-imaging and drug delivery in biological systems. Therefore, judicious crystal engineering along with structure-property relationship will lead to the fabrication of desire photosensitive MOFs. Herein, we attempted to incorporate categorical descriptions based on advance applications of photoresponsive MOFs considering wide range of recent publications.
