| titleOfInvention | A class of naphthocoumarin compounds and preparation methods and their application as photoluminescent materials |
| abstract | The invention discloses a class of naphthocoumarin compounds, a synthesis method thereof and an application as a photoluminescent material. The structural formula of this class of compounds is: In the formula, R represents hydroxyl, phenyl, phenylethynyl, or phenyl or phenylethynyl substituted by fluorine, trifluoromethyl, cyano, diphenylamino, etc.; R 1 and R 2 represent substitutions at any position on the benzene ring groups, such as hydrogen, C 1 -C 6 alkyl, C 1 -C 6 alkoxy, fluorine, chlorine, bromine, trifluoromethyl and the like. The present invention takes 1-(2-hydroxyphenyl)-2-phenyl-1-ethanone compound and Michaelis acid as raw materials, and reacts under acid catalysis conditions to obtain a compound in which R represents a hydroxyl group; The combined reaction yields compounds in which R represents other substituents, respectively. The compound of the present invention has photoluminescence properties, and is a new type of photoluminescence material, which can be printed on paper to form various anti-counterfeiting signs for preventing alteration or forgery, and can also be plastic-sealed on stainless steel sheets to serve as road signs at night indicator light. |
