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.
