中文摘要：
研究了4-（2＇-噻吩基）三联吡啶（化合物1）和联噻吩桥联双三联吡啶（化合物2）在不同溶剂中的光谱行为,化合物1显示出较强的溶剂极性效应,化合物1和2在酸性介质中由于强质子化作用,它们的吸收和发射光谱均发生了强烈的红移.使用紫外吸收滴定方法研究了它们和钴离子的配位作用,研究表明化合物1和2均可以与钴离子作用,分别形成1∶2和1∶1的配合物,其中化合物2和钴离子的配位作用可以生成有机金属聚合物.
英文摘要：
The spectroscopic properties of 4-（2＇-thiophenyl）terpyridine（1） and bithiophenyl bridged bis-terpyridine（2） are studied in organic solvents.Compound 1 shows stronger solvation effect than that of compound 2.The absorption and emission spectra of both compounds show strong red shift in acidic solvents due to strong protonation.UV-Vis titration shows that complexation of compound 1 and 2 with cobalt（Ⅱ） ion could be occured with coordination ratio of 1∶2 and 1∶1,respectively.The organometallic polymer can be formed when compound 2is treated with cobalt（Ⅱ） ion.
