中文摘要	the rare earth monophthalocyanine complexes, lnpccl and lnpc(oac)2 (ln = tb, ho, tm, lu, pc=phthalocyanine, oac = acetate), were synthesized. the electronic structures of the complexes have been studied by means of xps. the experimental results of binding energies for the complexes indicate that the bonds of the complexes have a certain covalent character depending on l-->ln charge transfer. this l-->ln charge transfer process of phythalocyanine complexes differs from that of crown ether complexes. both coordination and substitution are included in the former case, but only coordination in the latter. phthalocyanine ring is an electrophilic group and its electronegativity is large. so, the o1s binding energies of coordinating oxygen atoms of acetate in lnpc(oac)2 are larger than those of ln(oac)3. the magnitude of valent charge delocalized from ligand onto metal atom is dependent on electronegativity, coordination number, valence state and so on. because coordination number of ln in lnpc(oac)2 is larger than that in lnpccl and electronegativity of clin lnpccl is larger than that of o in lnpc(oac)2, the ln4d5/2 binding energies of lnpc (oac)2 are less than those of lnpccl.
