[Re(5-R-phen)(CO)3(X)]0/+, where phen = 1,10-phenanthroline, R = H, CN, COOH, COONH2, and X = Cl or pyridine, was prepared and characterized by elemental analyses, NMR, Vis/UV, emission and cyclic voltammetry. The complexes absorb in the near-ultraviolet region of the spectrum, emit between 550 and 600 nm with emission lifetimes between 150 and 500 ns, undergo irreversible oxidation at 1.45 V and a reversible reduction
摘要 一系列 [Re(5-R-phen)(CO)3(X)]0/+,其中 phen = 1,10-菲咯啉,R = H、CN、COOH、COONH2,X = Cl 或吡啶,通过元素分析、核磁共振、可见光/紫外、发射和循环伏安法制备和表征。配合物在光谱的近紫外区吸收,在 550 到 600 nm 之间发射,发射寿命在 150 到 500 ns 之间,在 1.45 V 下发生不可逆氧化,在 -1.30 V 附近发生 1,10-菲咯啉配体的可逆还原与乙腈中的 Ag/AgCl。
