本文以邻菲罗啉和二茂铁为原料,合成了一系列新Schiff碱型二茂铁衍生物:(C~10H~6N~2)C=N-N=CR-Fc,(C~10H~6N~2)C=N-C~6-H~4-N=CR-Fc,(C~10H~6N~2)C==N-C~6H~4-N=CR-Fe,(R=H,CH~3,Fc为二茂铁基;并对其进行了元素分析和光谱表征,该类二茂铁衍生物能有效地猝灭Ru(bpy) 的发光,Stern-Volmer图呈线性关系,双分子猝灭过程速率常数K~q为10°dm^3/mol.s^-3数量级.猝灭过程按电子转移还原机理进行.

A series of new ferrocene Schiff base derivatives, (C10H6N2)C:NN:CRFc, (C10H6N2)C:NC6H4N:CRFc, (C10H6N2)C:NC6H4C6H4N:CRFc, (R = H, Me; Fc = ferrocenyl), were prepared from 4,5-diazafluoren-9-one derivatives and ferrocene. The derivatives were characterized by elemental anal. and IR, UV, mass spectral, and 1H NMR spectral data. Ferrocene derivatives quench Ru(bpy)32+ with high efficiency. The Stern-Volmer plot is linear; the bimol. quenching rate constant has a magnitude of 109 dm3/mol譻. The quenching process of the Ru(bpy)32+ is carried out by a reductive mechanism.
