Photo-triggered transformation and surface temperature measurement. a, b Photo-triggered transformation of a thick plate-like crystal of enol-(S)-1 a upon ultraviolet (UV) light irradiation and b after stopping the irradiation (Supplementary Movie 2). Dotted lines indicate the propagation of the phase boundary. The scale bar is 0.5 mm. c Schematic illustration of the photo-triggered transformation. d Crystal surface temperature change upon UV light irradiation for 1 s monitored by an infrared (IR) thermography camera. The scale bar is 1 mm. e Time dependence of the surface temperature change at the cross point shown in d
