摘要: 本文介绍了一种新的敏化剂cis-(NCS)2-bis(2,2′-bipyridyl-3,3′-dicar-boxylate)ruthenium(Ⅱ)的合成,测定了它的吸收光谱及氧化还原电位,并将这种染料吸附到具有大比表面的TiO2纳晶电极上测量它的光电转换效率。另外,参照文献分别合成出cis-(NCS)2-bis(2,2′-bipyrdyl-4,4′-or 5,5′-dicarboxylate)Ru(Ⅱ)染料,测定它们的光电及光物理性质并以此为依据讨论了空间因素对敏化剂性质的影响。

Abstract: A new sensitizer named as cis-(NCS)2-bis(2,2′-bipyridy 1 3,3′-dicarboxylate) ruthenium(Ⅱ) has been prepared, spectroscopically characterized, and anchored to high surface area TiO2 nanocrystalline electrodes for measuring efficiency of energy conversion. In addition, cis-(NCS)2-bis(2,2′-bipyridy 1-4,4′-or 5,5′-dicarboxylate) ruthenium(Ⅱ) were prepared by literature methods, and their photophysical and photoelectrochemical properties were measured. From these data, steric effect on the properties of Ru polypyridyl complexes and energy conversion efficiencies has been investigated.

Key words: TiO2 nanocrystalline electrode, sensitizer, ruthenium polypyridyl
