We report the first photoinduced single-crystal-to-single-crystal SCSC phase transition of a gold complex 1 that involves strengthening of intermolecular aurophilic interactions. This is also the first solid state photochromism of gold complexes. Upon UV irradiation, blue-emitting crystals 1B of aryl gold I isocyanide complex 1 transform into the weakly yellow-emitting crystals 1Y. X-ray diffraction analyses exhibit that the phase transition proceeds in an SCSC manner. After phase transitiondoi:10.5940/jcrsj.57.226 fatcat:tdfs5fzftzcm5bluoiksghyanq
