“…The prediction of the oxidation product of metalloporphyrins is not trivial, highly debated in literature and depends on the nature of the metal cation, the porphyrin substituents, the axial ligands and the physical state (solution, gas or solid) . With redox active metal cations the oxidation of the metal center itself can occur …”

Metalloporphyrin tapes form in a solvent-free oxidative chemical vapor deposition process on glass substrates. The metal center (M = Ni II , Cu II , Zn II , Co II , Pd II , Fe III Cl, 2H) in the 5,15-disubstituted porphyrin monomer affects the initial C-C coupling step and consequently the formation of triply or doubly linked porphyrin tapes as well as the interchain interaction in the tape as shown by optical spectroscopy, high resolution

Oxidative chemical vapour deposition of (5,15‐diphenylporphyrinato)nickel(II) (NiDPP) with iron(III) chloride as oxidant yielded a conjugated poly(metalloporphyrin) as a highly coloured thin film, which is potentially useful for optoelectronic applications. This study clarified the reactive sites of the porphyrin monomer NiDPP by HRMS, UV/Vis/NIR spectroscopy, cyclic voltammetry and EPR spectroscopy in combination with quantum chemical calculations. Unsubstituted meso positions are essential for successful polymerisation, as demonstrated by varying the porphyrin meso substituent pattern from di‐ to tri‐ and tetraphenyl substitution. DFT calculations support the proposed radical oxidative coupling mechanism and explain the regioselectivity of the C−C coupling processes. Depositing the conjugated polymer on glass slides and on thermoplastic transparent polyethylene naphthalate demonstrated the suitability of the porphyrin material for flexible optoelectronic devices.
