Synthesis and Photoelectric Property of Complexe C_(60)Pd(Ph_2PCH_2CH_2PPh_2)

In the present work, the fullerene complexe C60Pd(Ph2PCH2CH2PPh2) was perpared by the method of ligand substitution via the reaction of C60 with Pd(Ph2PCH2CH2PPh2)2 in nitrogen atmosphere under refluxing, and the title compound was characterized by the methods of elemental analysis , FT-IR, UV-vis, XPS,XRD. The result shows that the structure of purposeful product is that the Ph2PCH2CH2PPh2 took up two coordination sites of the central metal, and C60 took up another two sites in σ-π feedback pattern. Meanwhile the properties on redox and the thermostability were studied, the redox research indicates that the reduction potential of the complexe is more negative than that of the pure C60.And the research on the photovoltaic effect for C60 Pd(Ph2PCH2CH2PPh2) complex which forming n+n heterojunction with GaAs electrode in photoelectrochemical cell shows that the photoelectric property of C60Pd(Ph2PCH2CH2PPh2) is excellent, especially in the Fe(CN)63-/Fe(CN)64- redox couple mediator. The photovoltaic property of C60Pd(Ph2PCH2CH2PPh2) electrode at 1μm for thickness of C60Pd(Ph2PCH2CH2PPh2) is the best, the photopotential value is up to 367 mV.
