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.
