Abstract

The Ni(II), Pd(II) and Pt(II) complexes with 2,3,9,10,16,17,23,24-octapropyltetrapyrazinoporphyrazinate were prepared. Their absorption spectra and cyclic voltammograms (CV) in CH₂Cl₂ were measured. The two absorption bands corresponding to the Q and B bands of metallophthalocyanines are observed in the 500-660 and 270-400 nm ranges, respectively. The two redox couples indicating reversible one-electron transfer processes appear in the reduction side of the CV. Irreversible oxidation with decomposition of the complex molecule was confirmed by a controlled-potential electrolysis experiment. The spectral and electrochemical properties of these complexes reflect the energy gap between the highest occupied and lowest unoccupied molecular orbitals of the ligand.
