Abstract

Syntheses of phthalocyaninatoiron complexes, Fe(Pc^b)L₂ and [Fe(Pc^b)L]_a {where Pc^b = tetra-tert-butylphthalocyaninato, L = 4,4′-azopyridine (4,4′-APy) or octafluoro-4,4′-azopyridine (4,4′-FAPy)}, were carried out. These complexes were characterized with TG/DTA, ¹H NMR, UV-visible spectroscopy, and cyclic voltammetry. Voltammetric measurements of soluble Fe(Pc^b)L₂ in benzene solutions revealed that coordination of axial ligands on Fe(Pc^b) greatly influenced oxidation potentials of the central metal moiety. The correlation between conductivities of polymeric [Fe(Pc^b)L]_a complexes and bandgaps determined by the voltammetric measurements was identified.
