Self-aggregated phosphorescent platinum(II) polymeric material from modified poly(4-vinylpyridine).
A solvochromic material made from incorporation of photoluminescent Pt(II)([formula: see text]) 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 pi-stacking of the Pt([formula: see text]) moieties, which is affected by medium polarity.
