Oxazole molecule photo-switching fluorescent modulation material

The invention discloses an oxazole molecule photo-switching fluorescent modulation material 5-(piperidine-1-yl)-2-(1,3,3-trimethylindoline-2-yl)naphtho-[1,2-d]oxazole. According to the invention, the oxazole molecule is a combination of an indole ring and a naphthooxazole ring, the naphthalene ring of the latter is provided with a piperidine substituent group, and the general molecular formula is C27H29N30. After being subjected to ultraviolet irradiation, the oxazole molecule presents typical photochromism, and can be singly used as a photochromic material. Before and after the color change, the oxazole molecule presents distinct photoluminescenece properties, and the corresponding fluorescence emission intensity presents a characteristic of varying with the color change degree. Thus, the oxazole molecule can be used as a photo-switching fluorescent modulation material.
