2,6-双(1-苯并咪唑基)吡啶的合成及光谱性能研究
Synthesis and Optical Properties of 2,6-bis(benzimidazol-1-yl) Pyridine
【摘要】 以苯并咪唑与2,6-二溴吡啶为原料,经过Ullmann反应合成了2,6-双(1-苯并咪唑基)吡啶.目标化合物经IR、1 H NMR、13 C NMR和元素分析表征.对所合成目标化合物的紫外及荧光光谱进行了研究,它们的最大紫外吸收峰及荧光发射峰随着溶剂极性的增大而发生了红移.
【Abstract】 2,6-bis(benzimidazol-1-yl) pyridine was synthesised from benzimidazole and 2,6-dibromopyridine as starting material through a modified Ullmann reaction in DMF.The structure of the objected compoud was characterized by IR,1H NMR,13C NMR and elemental analysis.The UV-Vis absorption and Photoluminescence spectra of the molecule were studied.The significant red-shift of the absorption band and emission band were observed as the solvent polarity is increased.
