| titleOfInvention | Spirooxazine Compounds and Methods for Making the Same |
| abstract | The present invention relates to a novel spirooxazine compound having a photochromic property of the following structural formula obtained by reacting trimethylindolin or an indolenium derivative with a nitrozo arene derivative, and a method for preparing the same.n n n n n n n n Wherein R 1 is an alkyl group having 9 to 20 carbon atoms, ring A represents a substituted or unsubstituted benzene ring, and ring B represents a substituted or unsubstituted quinoline ring. Compounds having such structural formulas have a spirooxazine as a basic structure to introduce hetero elements and at the same time have a high carbon number chain to increase the degree of discoloration upon exposure to sunlight or ultraviolet rays and to form films in various solvents or polymer matrices. Can improve the degree. |
