摘　　要：以2-醛基吡啶和邻苯二胺为起始原料,经两步反应合成了新型的BOPIM(Boron 2-(2-pyr-idyl)imidazole complex)荧光染料,并通过1 H NMR,13C NMR,高分辨质谱进行了结构鉴定。对该化合物的紫外-可见吸收及荧光光谱测试表明:该染料有较高的荧光量子产率,相对较大的Stokes位移;且荧光性能呈现明显的溶剂效应。Novel BOPIM（Boron 2-（2-pyridyl）imidazole complex） dye was prepared through two-step reactions,starting from 2-pyridinecarbox-aldehyde and o-phenylenediamine.The structure of the BOPIM dye was proved by 1H NMR,13C NMR,and HR-MS.UV-Vis absorption and fluorescent measurements indicated that prepared the BOPIM dye exhibited high fluorescent quantum yield,comparatively large Stokes shift and also solvent-dependent fluorescent property.
