"Structure of a photochromic crystal of 1,2-Bis(2-ethyl-5-phenyl-3-thienyl) perfluorocyclopentene. The structure of the crystal after the 400nm laser-irradiation is different from that in the blue phase in solution."

"Experimental setup for time-resolved x-ray diffraction of photochromic crystals. Inset: Time chart of laser irradiation and the corresponding phases of a sample."

"(i) Time-resolved rocking curve for hkl=060 of a diarylethene crystal (c),together with the color (b) and a time-chart of laser-irradiation (a). (ii) The x-ray diffraction intensity for single pulse irradiation. Response time of lattice expansion was found to be less than 0.5ms
