Abstract: Cyclic voltammetry and in-situ UV-Visible spectroelectrochemical behavior of (TbPc)Fe(Ⅲ)Cl, (TbPc)Fe(Ⅲ)ClO4 and (TbPc)Zn(Ⅱ) are reported. Five redox steps of Fe(Ⅳ)/radical cation, Fe(Ⅳ)/Fe(Ⅲ), Fe(Ⅲ)/Fe(Ⅱ), Fe(Ⅱ)/Fe(Ⅰ) and Fe(Ⅰ)/radical anion in THF were observed. The existence of un usual oxidation state of Fe(Ⅳ) is attributed to the axial coordination of Cl- anion. A mechanism for the redox reactions has been proposed.

Key words: iron phthalocyanine, in-situ spectroelectrochemistry
