In the present work, four new D-A compounds, H2Po-C-70, H2PP-C-70, ZnPo-C-70 and ZnPP-C-70 were prepared by 1,3 dipolar cycloaddition reaction of C-70. The new D-A compounds were characterized by UV-Vis, FTIR, ESI-MS, as well as elemental analysis. The results show that four novel types of covalently linked porphyrin-fullerene dyads were formed. The photovoltaic effect (PVE) of the new D-A compounds on GaAs electrode in electrochemical photovoltaic cell were measured. The results show that the values of Delta V and Delta I for H2P-C-70/GaAs and ZnP-C-70/GaAs electrode are much greater than those for pure GaAs electrode. So that the photoelectric properties for the new D-A compounds are excellent. In addition, the photoelectric property of a H2P-C-70/GaAs and ZnP-C-70/GaAs electrode is related to the thinkness of the sample film and the media.
