摘要
以四氯化碳、苯、甲苯及铜粉等为主要原料,在四氯化碳过量下,无水三氯化铝与苯的量之比1:2,反应温度5~10℃时,反应2 h后得二苯二氯甲烷,接着在甲苯为溶剂条件下,二苯二氯甲烷与铜粉回流4 h得到四苯乙烯;观测四苯乙烯在不同光照条件下的发光颜色,同时在最佳激发波长条件下研究固态四苯乙烯的荧光发射强度。结果表明:四苯乙烯合成产率达61%,具有很强的荧光发射强度,且在紫外光照射下显现出很强的蓝色荧光,展现出其在固态发光、传感器领域中的应用潜能。
The ratio of anhydrous aluminum trichloride to benzene is 1： 2, and the reaction temperature is 5 - 10 ℃ when carbon tetrachloride, benzene, toluene and copper powder are used as main raw materials, of which carbon tetrachloride is excessive. After 2 hours, diphenyldichloromethane is obtained, and then tetramethylene is obtained by refluxing the diphenyldichloromethane and copper powder for 4 hours under toluene. The color of the tetrastyrene at different light conditions is observed. The fluorescence emission intensity of solid tetrasilene is studied under the optimum excitation wavelength. The results show that the yield of tetrastyrene is 61%and it has strong fluorescence emission intensity and shows strong blue fluorescence under ultraviolet light irradiation, which reveals its potential in solid state luminescence and sensor field.
