Abstract

Syntheses of phthalocyaninatoiron complexes, Fe(Pcb)L2 and [Fe(Pcb)L]a {where Pcb = 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(Pcb)L2 in benzene solutions revealed that coordination of axial ligands on Fe(Pcb) greatly influenced oxidation potentials of the central metal moiety. The correlation between conductivities of polymeric [Fe(Pcb)L]a complexes and bandgaps determined by the voltammetric measurements was identified.
