Conductive polymeric porphyrin films have been obtained by oxidative electropolymerization of two major groups of porphyrin complexes. The first group is composed of several novel porphyrin systems: meso-(2.2)paracyclophanyltriphenylporphyrin, T(PCP)P, with Fe, Co, Mn, and Ni as central metals. The second group comprises the free-base and metalated tetrakis(p-(diethylamino)phenyl)porphyrins with Cu, Fe, Co, Mn, Ni, and Pd as central metals and the Ru carbonyl pyridinate analogue of this porphyrin group with carbonyl and tert-butylpyridine (t-Bupy) as axial ligands, general formula M(p-Et{sub 2}N)TPP. This work focuses on two important aspects of the porphyrin films, their surface morphology as viewed by scanning electron microscopy and their catalytic activity in regard to the electrocatalytic oxidation of hydrazine. The films presented in the morphology discussion are those electropolymerized from T(PCP)P, Ru(CO)(p-Et{sub 2}N)-TPP(t-Bupy), and Co(p-Et{sub 2}N)TPP. The films used in the catalytic studies on hydrazine oxidation are those electropolymerized from PCPP, CoPCPP, both T(PCP)P and M(p-Et{sub 2}N)TPP with Co, Mn, and Ni as central metals, and Ru(CO)(p-Et{sub 2}N)TPP(t-Bupy).
