The electro‐oxidation of Ni(II)TVyPP and Zn(II)TVyPP in organic solvent (CH 2 ‐C1 2 ) leads to the deposition of ca. 500 monolayer equivalents of electroactive porphyrin films which have been characterised by cyclic voltammetry. The films are stable towards organic solvents and aqueous acids and bases, but are removed by treatment with hot concentrated acids. The Laser Raman spectrum of NiTVyPP film indicates that all the four vinyl groups are saturated. No film is formed if the metal and not the ring is oxidised.
