摘　　要：合成了铼联吡啶和钌三联吡啶两个新的太阳能电池光敏染料 ,对其结构进行了表征 ,并对染料的光、电化学性能进行了测定 .两染料在可见光区的最大吸收波长分别为 382和 4 76 nm ,发射波长分别为 6 2 2和6 72 nm;在较宽的电位范围内具有很好的氧化 -还原可逆性 ,Re( / )具有比 Ru( / )更高的氧化电位 ,可为电子传递提供更大的驱动力 .它们都具有良好的稳定性 ,适合于用作太阳能电池的光敏剂 .There has been a growing effort to convert solar energy into electricity in recent years. In order to get a stable solar cell system and acquire a high incident photon-to-current conversion efficiency(IPCE), two novel rhenium(Ⅰ) bipyridyl and ruthenium(Ⅱ) tris-bipyridyl photosensitive dyes were synthesized, the ethoxycarbonyl group in the dyes could be employed for covalently linking to the surface of the nanostructured TiO 2. Their structures, photophysical and electrochemical properties were studied. The UV-Vis absorption maxima were 382 and 476 nm; emission maxima were 622 and 672 nm, respectively. The Re(Ⅰ/Ⅱ) oxidation potential is significantly positive than that of Ru(Ⅱ/Ⅲ) which provides a larger driving force for electron transfer. The results show that they both have proper redox potentials, enough stability and are suitable for being used as photosensitizers of solar cells.
