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

摘要

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.
