Abstract

The present invention relates to an indolinospirobenzoxazine compound, its synthesis method and application. Said synthesis method includes the following steps: under the protection of nitrogen gas dissolving I-(R1)-2,3,3-trimethyl-pseudoindole iodine salt in anhydrous ethyl alcohol adding hexahydropyridine whose concentration is 0.5 wt%-10 wt% catalyst quantity, under the condition of refluxing drop-adding anhydrous ethyl alcohol solution of 2-nitroso-phenol derivative or 2-nitroso-3-R3-5-R2-phenol which is identical to 1-(R1)-2,3,3-trimethyl-pseudoindole iodine salt in gram molecular weight, drop-adding while distilling, after drop-addition continuously refluxing, concentrating, making the above-mentioned silicon gel column so as to obtain the invented product which can be used for making photochromic materials.

Description

technical field

[0001] The invention belongs to the technical field of preparation and application of indoline spirooxazine photochromic materials, and in particular relates to indoline spirobenzoxazine compounds and their synthesis methods and applications. Background technique

[0002] Organic photochromic materials have broad application prospects. Compared with inorganic materials, they have the advantages of fast response, easy processing, and low cost.

[0003] Indoline spirooxazine compounds are a class of photosensitive materials with certain application value due to their good fatigue resistance and weather resistance, and have been extensively studied.

[0004] Photochromism can be roughly described as follows: <chemistry num="001"> <chem file="02123486_cml001.xml" / > < / chemistry>

[0005] Photochromic substance A, here is an indoline spirooxazine compound, in a certain wavelength of light (hv 1 ) under the irradiation,...
