摘要：

1',3',3'-Trimetliyl-6-nitro-8-pyridiniomethylspiro[2H-[1]benzopyran-2,2'-indoline] chloride (1) was synthesized. Single crystals (crystal hydrates) of the open merocyanine form of compound 1 were obtained under the dark conditions, and their crystal structure was studied. On irradiation with visible light compound 1 crystallizes from propan-2-ol in the polycrystal-line closed form. The spectral and photochemical properties Of Compound 1 in the polycrystal-line state and the kinetic characteristics on thermal transformation of the closed form to the open form were Studied.
