采用一锅反应法,以氰乙酸乙酯、水杨醛和2-氨基苯硫酚为原料,在苯甲酸为催化剂的条件下,通过对反应时间的控制,同时合成出两种不同类型的荧光材料3-(2-苯并噻唑)香豆素和2-苯并噻唑-2-苯酚.该合成方法具有操作简单、反应条件温和、资源利用率高等特点.通过1H NMR,IR和X-射线单晶衍射等对这两种化合物结构进行了表征,并对它们的紫外吸收光谱和光致发光光谱进行了测试和分析,这两种化合物分别发射出明亮的蓝光(450 nm)和绿光(520 nm).%Two different fluorescent materials containing benzothiazolyl moiety, 3-( benzothiazol-2-yl) coumarin (BTC ) and 2-( benzothiazol-2-yl) phenol ( BTP) , were synthesized synchronously using ethyl cyanoacetate, salieylaldehyde and 2-aminothiophenol as the starting materials under the catalysis of benzoic acid by one-pot reaction. The method has the advantages of mild reaction condition, easy processing and low waste. The structures of the products were characterized by IR, 1H NMR spectra and single crystal X-ray crystallography. Their UV-vis absorption and photoluminescence spectra were investigated. They exhibit strong blue emission (450 nm) and green emission (520 nm) in solutions, respectively.
