摘　　要：以5-氯-2-氨基苯甲酸和邻苯二胺为原料,经两步缩合反应,合成了目标化合物,6-氯-2-[5-氯-2-(4-对甲苯磺酰胺基)]苯基-[3,4]-苯并咪唑-[1,3]-喹唑啉(化合物B)。通过核磁共振氢谱(1 H-NMR)、质谱(MS)、傅里叶变换红外光谱(FT-IR)和元素分析确定了目标化合物的结构。借助紫外-可见吸收光谱、荧光光谱和热重分析研究了它的光学和热学性能。结果表明,目标化合物在紫外光激发下显示出很强的绿色荧光发射能力,同时具有很大的斯托克斯位移(Stokes Shift)和良好的光、热稳定性,有望在荧光防伪技术中得到潜在应用。A novel compound, 6-chloro-2-[- 5-chloro-2 （ 4-methyl benzenesulfonamido ） ] pheny-benzo[3,41imidazo [1,3]quinazoline, was synthesized by the reaction of 5-chloride-2-aminobenzoic acid and o-phenylenediamine. Its structure was characterized by1 H-NMR, MS, FT-IR and elemental analysis. Its optical and thermal properties were studied in detail by UV-Visihle and fluorescent spectroscopy and thermogravimetry analysis. The results indicated that the compound showed strong green fluorescence emission ability under the excitation of ultraviolet light, exhibiting large Stokes shift and significant optical and thermal stability. The compound was expected to be a potential candidate for applications in fluorescent anti-counterfeiting technology.
