在混合酸的催化条件下,合成了2-(4-碘苯基)苯并咪唑(PIBB),产率为80.5%。产物经元素分析、质谱、1HNMR谱表征。研究了PIBB分子中苯并咪唑基团和对碘苯基的特征荧光峰和荧光寿命,发现PIBB化合物可发射多种波长强荧光,是良好的荧光材料。
Under the catalysis of mixed acid, 2-(4-iodophenyl)benzimidazole(PIBB) was synthesized and the yield was 80.5%. The product was characterized by elemental analysis, mass, and tHNMR spectra. The characteristic fluorescence peaks and lifetimes of benzimidazolyl group and p-iodophenyl group were studied. It was found that PIBB emitted multiwavelength strong fluorescence, it was a very good fluorescent material.
