The ligand and complexes were characterized by means of FT-IR, Uv-Vis, 1HNMR, ESI-MS and elemental analysis. The photoelectricity transform performance of the compounds was studied.The result indicated that the photovoltaic effect of （n+n） heterojunction electrode formed by MP-C60/GaAs was super, especially in the I2/I3- and O2/H2O redox couples, and photovoltaic potential was preferable.The photovoltaic performance of a MP-C60/GaAs electrode at 1-2 μm thinck MP-C60 film of appeared peak value.展开更多

The results prove the presence of C-Co and -OH groups in the resultant, and coovalent of Co bonding to C 60. The apparent charge distribution of the resultant appeaers to be Co 2+C - 60(OH) -, and there are three kinds of carbons with different electron density. The result of redox experiment indicates that the reduction potential of the compound is more negative than that of pure C 60.展开更多
