A Room‐Temperature X‐ray‐Induced Photochromic Material for X‐ray Detection

A color change: X-ray-induced photochromic species are rare and can be used for detection of X-rays. A highly robust X-ray-sensitive material with the discrete structure of a metal–organic complex has been found to show both soft and hard X-ray-induced photochromism at room temperature (see picture). A new ligand-to-ligand electron-transfer mechanism was proposed to elucidate this photochromic phenomenon.
