摘要：

以2,2’-联吡啶取代物为原料,设计合成了两种新的具有不同配体的联吡啶钌光敏染料;利用红外吸收光谱和核磁共振氢谱对各光敏染料及其中间物进行了结构表征.研究了两种光敏染料的光伏性能,结果表明两者性能良好:两者在可见光区分别存在最大吸收波长521nm和545nm,带隙计算值分别为1.87eV和1.58eV;将它们制成DSSCs器件,在模拟太阳光照射下(AM1.5),其能量转换效率分别达到了10.21%和9.97%.

Two new ruthenium bipyridine photosensitive dyes with different ligands were synthesized from substituted 2, 2？-bipyridine. The structures of the dyes and their intermediates were characterized by IR and 1HNMR. The photophysical and electrochemical properties of the dyes were studied, and the results were satisfactory： the maximum absorption wave -lengths in the visible region of them were 521 nm and 545 nm, and the calculated values of the band gaps were 1. 87 eV and 1. 58 eV. The photoelectric conversion efficiencies of the dyes based DSSCs werelO. 21% and 9. 97%.
