The triplet state in Pt-acetylide oligomers, polymers and copolymers☆

Abstract Platinum acetylide oligomers and polymers are π-conjugated materials that display luminescence from the triplet exciton. This property makes platinum acetylides useful for exploring the properties of the triplet state in π-conjugated systems. In the present review we describe the excited state properties of a series of Pt-acetylide oligomers and polymers with an emphasis placed on understanding structure–property relationships for the triplet state in π-conjugated systems.
