铼配合物光异构化的拉曼和红外光谱研究

光敏分子和它们在光作用下发生的异构化一直是分子光化学研究领域中感光趣的课题。含有光敏基团的铼配合物的一个新颖特性是其具有电致发光性质。为弄清结构与功能性质的联系 ,本文研究了 Re(CO) 3 (2 ,2 '-联吡啶 ) 4- (4'-硝基苯己烯基吡啶 ) ]高氯酸盐的 FT-Raman和 FT- IR光谱 ,指认了光照前和光照后的拉曼位移。讨论了这些变化与金属到配体电荷转移的联系

FT-Raman and FT-IR Study on the Photo-isomerization of the Re Complex

Photosensitive molecules and their photo isomerization have been extensively investigated in the field of molecular photochemistry. A novel feature of the Re complexes with photoresponisive ligands is its electro luminescent property. FT Raman and FT IR spectra of Re(CO) 3(2,2' bipyridine)4 ｛4 nitrostyryl)pyridine]ClO 4were studied to better understand the relationship between its structure and function. The Raman shifts of the comlex were assigned before and after photo isomerization. The possible association of changes in the Raman shifts with charge transfer from metal to ligand was also discussed.
