    Abstract

    Phosphorescent conjugated polymers consisting of alternating p-phenylene-ethynylene and 'para-' or 'meta-type' Pt(II)-salphen luminophore units have been synthesized. Side-arms bearing different substituents (n-alkoxy and acetylated-sugar) have afforded contrasting emission properties that are attributed to the polymer conformation, extent of π-stacking interactions and differences in chemical structure. Intriguing selectivity in luminescent sensing of metal ions has been observed. Phosphorescent conjugated polymers consisting of alternating p-phenylene-ethynylene and ' para-' or ' meta-type' Pt(II)-salphen luminophore units display contrasting emission properties that are dependent on the side-arm substituents and chemical structure, polymer conformation and degree of π-stacking interactions. Selectivity for Cu 2+ is apparent in luminescent sensing of metal ions. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
