Self-aggregated phosphorescent platinum(ii) polymeric material from modified poly(4-vinylpyridine)

Abstract

A solvochromic material made from incorporation of photoluminescent Pt(II)(C^N^N) moieties into commercially available homopolymer poly(4-vinylpyridine) exhibits different emission energies, due to different degrees of self-aggregation in various solvents and as thin film upon exposure to vapour of different volatile organic compounds (VOC); self-aggregation enables intra- and intermolecular interactions arising from π-stacking of the Pt(C^N^N) moieties, which is affected by medium polarity.
