Synthesis, structure control and functions of polymers containing conjugated transition metal complex moieties

Abstract

Polymers containing conjugated platinum (Pt) complex moieties in the main/side chains are potential high-performance materials that combine the catalytic and photoelectric functions of Pt complexes with the photoelectric properties and formability of π-conjugated polymers. The present article overviews the synthesis of Pt-containing polymers using a variety of polymeri-zation methods, including dehydrochlorination coupling polymerization of PtL2Cl2 (L: ligand) with HC≡C–Ar–C≡CH (Ar: arylene) and ring-opening metathesis polymerization of nor-bornene monomers bearing Pt complex moieties. In addition, structural control by in-tra/intermolecular Pt–Pt, Pt–π, π–π, hydrogen bonding and van der Waals interactions are de-scribed. Finally, the review describes the development of applications of these materials, in-cluding catalysis for hydrosilylation and oxidation of alkenes, as well as photon upconversion, circularly polarized luminescence, mechanochromism and chiral recognition.
