Abstract: 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 C{60 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 C{60. 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)^3-₆/Fe(CN)^4-₆ 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.
