Abstract

A polymer ([Pt]–ZnP)n (ZnP = bis-meso-(hexahexyltruxene)zinc(II) porphyrin; [Pt] = trans-bis(phenylacetylene)bis(tributylphosphine)platinum(II)) was prepared from bis-meso-(hexahexyltruxene)zinc(II) porphyrin and trans-dichlorobis(tributylphosphine)platinum(II) and exhibits fluorescence and phosphorescence from truxene (Tru) and ZnP, and phosphorescence from [Pt] all at once. Evidence for singlet and triplet energy transfer Tru  ZnP (slow), [Pt]  ZnP (fast) is provided indicating inter-chromophore interactions. DFT computations indicate strong MO coupling between [Pt] and ZnP.
