摘　　要：本文将电子供体三苯胺通过大π共轭链引入到联吡啶上合成三苯胺取代的联吡啶钌金属配合物。在加酸和粘度实验中,三苯胺的构型发生改变,导致其发射光谱、循环伏安曲线改变;加入电子受体或者电子供体,其瞬态吸收光谱也发生改变。从而间接证明其存在着分子内和分子间电子转移。In this paper we have synthesized and characterized polypyridyl ruthenium complexes which were substituted by triphenylamine group through π-conjugated bonds. The intramolecular and intermolecular electron transfer between triphenylamine and ruthenium have been studied indirectly through the change of emission spectra,cyclic voltammetric curve and transient absorption trance with the protonation of amine group,the viscidity of the solvent and addition of electron donor or electron acceptor.
