摘　　要：设计合成了 2 ,2′ 联吡啶 4,4′ 二羧酸乙酯与过渡金属铼的系列络合物 [fac Re( 4 ,4′ di COOEt bpy) (CO) 3 (Xpy)PF6](其中bpy =2 ,2′ 联吡啶 ;py =吡啶 ;X =3 CH3 ,3 OH ,3 NH2 和H) ,对它们的电化学性能、紫外可见吸收、荧光激发和发射光谱进行了研究 .结果表明 ,随着吡啶环上取代基供电子能力的增强 ,H <CH3 <OH <NH2 ,Re(II/I)的氧化电位降低 ,减小了电子回传的驱动力 ;MLCT最大吸收波长变化不大 ,最大发射波长略有蓝移 ,荧光强度减弱 。A series of rhenium(I) 2,2′-bipyridyl complexes [fac-(4,4′-di-COOEt-bpy)Re(CO) 3(Xpy)PF 6] (bpy=2,2′-bipyridine; py=pyridine; X=3-methyl, 3-hydroxy, 3-amino, H) were synthesized. Their electrochemical properties, ground state electronic spectra and emission spectra were studied in acetonitrile. As the X group became more electron donating from H to 3-methyl, 3-hydroxy or 3-amino, the Re(II/I) oxidation potentials declined, the MLCT absorption maximum of the complex was changed little, the emission maximum blue-shifted, and the emission intensity and the fluorescence lifetime were decreased.
