Abstract: Photochromic spirooxazine compound was synthesized using o-carboxyl phenylhydrazine hydrochloride and methyl isopropyl ketone as the starting materials.The structure was characterized by elemental analysis,IR,1H NMR spectra and X-ray single crystal diffraction,The photochromism was investigated.The results show that,the color of this material can be changed under the irradiation of ultraviolet light.Using microwave the reaction time is greatly shortened.
