This paper describes the preparation, characterization and conductivity of the self-assembly films of two newly synthesized bridged-porphyrins [FeTPPCN](n) and [CoTPPpz](n). The bridged-porphyrins are bonded covalently to the gold surface or the foundational film surface on the gold substrate. The films are characterized by Auger electron spectroscopy and X-ray photoelectron spectroscopy. Raman studies reveal that the long axis of the CN-porphyrin is perpendicular to the surface and that of pyrazine-porphyrin tilts on the surface. The conductivity in the film normal direction is 9.1 x 10(-4) S cm(-1) and 3.8 x 10(-4) S cm(-1) respectively for [FeTPPCN](n) and [CoTPPpz](n) after doping with iodine.
