A new photochromic Gd-MOF with photoswitchable bluish-white to greenish-yellow emission based on electron transfer

Abstract

Utilization of photochromism in photo-switchable white-light emitters (WLEs) is a challenging task. In an effort to achieve this, we have recently developed a new Gd-MOF using a photoactive pyridinium-based inner salt. The compound shows interesting photoswitchable bluish white light to greenish yellow light emission as a result of electron transfer, a phenomenon that has not been observed previously in photochromic crystal compounds.
