Abstract

The rather complex emission pattern of polymers of the types ([Pt]-[Q])n and ([Pt]-[DAB])n ([Pt] = trans-bis(tributylphosphine)bis(phenylacetynyl)platinum(II); [Q] = substituted quinone diimine; [DAB] = substituted diaminobenzene; X = H, F, Cl) as organometallic versions of polyaniline, PANI, have been addressed using various models. Both the fluorescence and phosphorescence spectra at 77 K originate from [Q] or/and [DAB] residues as the main component or “impurities”, regardless of the polymer or model studied. However at 298 K, this chromophore is completely silent and only a weak fluorescence arising from the [DAB] fragment is observed, either as a part in the chain but also as an unavoidable impurity due to the nature of the redox aspects of the two units.
