| titleOfInvention | Luminescent material naphtho oxazole derivative and preparation thereof |
| abstract | The invention discloses a fluorescent material naphtho-oxazole derivative and a method for preparing the same. The method comprises the following steps: 1) adding 2-hydroxy-3-naphthoic acid, ortho-mercapto-aniline and toluene into a reactor, heating and refluxing reactants for a certain period of time, dripping PCl3 into the reactants after slight cooling , performing refluxing reaction continuously, and filtering, washing and drying the reactants; 2) reacting dry 2-hydroxy-3-(2-benzothiazolyl) naphthalene with glacial acetic acid by adding NaNO2 at a temperature of between 1 and 5 DEG C, and filtering, washing and drying the reactants; 3) heating and reacting dry 1-nitroso-2-hydroxy-3-(2-benzothiazolyl) naphthalene, water, 10 percent hydrochloric acid with stannous chloride, and filtering, washing and drying the reactants; and 4) heating and reacting dry 1-amino-2-hydroxy-3-(2-benzothiazolyl) naphthalene, acyl chloride compound with N-methyl pyrrolidone, and performing filtering, water washing and air drying on the reactants to obtain a naphtho-oxazole fluorescent material. The method has the advantages of easy availability of raw materials, low price, simple operation, and easy industrialization; besides, the compound prepared by the method has high fluorescence quantum yield. |
