一种新型多吡啶钌配合物的合成及其太阳光谱响应特性

摘要

A new ferrocene-thiazole derivative, 4-ferrocene-2-(2-pyridine)yl-thiazole( 2-FPT), was prepared by the coupling reaction, oxidation reaction, bromine-acylation reaction and cyclization from ferrocene and 2-picolinamide. A novel photoconductive dye, Ru(dcbpy) 2 (2-FPT) (1), was synthesized by the coordination reaction of 2-FPT with dichloro(p-cymene) ruthenium( Ⅱ ) using 2-FPT as the first ligand and 2,2'-bipyridyl-4,4'-biformic acid(dcbpy) as the second ligand. The structures were characterized by elemental analysis and TOF-MS. Response property to solar spectrum of 2-FPT and 1 were exhibited by UV-Vis. The results showed that 1 exhibited a wide response to the solar spectrum although the MLCT band was not so strong.%以二茂铁和2-吡啶甲酰胺为原料,经偶联、氧化、溴乙酰化及环合反应制备了一种新型的二茂铁噻唑衍生物4-二茂铁-2-(2-吡啶)基噻唑(2-FPT);以2-FPT为第一配体,2,2'-联吡啶-4,4'-二甲酸(dcbpy)为第二配体,与二异苯丙基氯化钌进行配位,合成了一种新型的光敏化染料Ru(dcbpy)2(2-FPT)(1),其结构经元素分析和时间飞行质谱表征.用UV-Vis对2-FPIT和1的太阳光谱响应特性进行研究,结果表明:1的MLCT带强度不十分明显,但具有宽范围的太阳光光谱响应.
