Synthesis and Photoelectric Property of Complexes η2-C60[Ru(NO)(PPh3)]n

Abstract

Abstract: The fullerene complexes, η²-C₆₀[Ru(NO)(PPh₃)]_n, were prepared by the reaction of C₆₀with Ru(NO)₂(PPh₃)₂under a nitrogen atmosphere and refluxing. The new complexes were characterized by means of elemental analysis, IR, XPS, electronic spectra, ³¹PNMR and ¹³CNMR. The results show that the η²form complexes can be formed by C₆₀bonding to Ru(NO)₂(PPh₃)₂in the σ-π way and there is hy-perconjugation effect in the molecule. So electrons will flow easier and photoelectric properties for the new compounds are expected. In addition, the structures of the complexes were supposed. The ruthenium is 4-coordinated in the complexes, bonding to two carbon atoms, one PPh₃and one NO. The photoelectric effect of the fullerene complexes was also studied. The results show that the photoelectric properties of the fullerene complexes are better than those of pure GaAs electrode, and is related to thickness of the sample film, the media and the number of the bonded organometallic groups.
