Abstract
Syntheses of phthalocyaninatoiron complexes, Fe(Pc b)L 2 and [Fe(Pc tb) L] n 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. Vpltammetric measurements of soluble Fe(Pc b)L 2 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] n complexes and bandgaps determinedby the voltammetric measurements was identified.
