Synthesis and Photoelectric Property of Four New D-A Compounds

Abstract

Abstract: In the present work, four new D-A compounds, H₂P_o-C₇₀, H₂P_p-C₇₀, ZnP_o-C₇₀ and ZnP_p-C₇₀ were prepared by 1,3 dipolar cycloaddition reaction of C₇₀. 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 ΔV and ΔI for H₂P-C₇₀/GaAs and ZnP-C₇₀/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-C₇₀/GaAs and ZnP-C₇₀/GaAs electrode is related to the thinkness of the sample film and the media.

Key words: Porphyrin, C₇₀, D-A compound, Photoelectric property
