In this study, we report the synthesis and characterization of a new bis(pyridyl)-coordinated platinum(II)-containing metallopolyyne polymer. It is found that this metallopolymer can act as a precursor towards the synthesis of Pt nanoparticles upon pyrolysis (600 °C, 5 h). The resultant nanoparticles were characterized by transmission electron microscope (TEM), energy-dispersive X-ray analysis (EDXA)

approach to reduce the singlet-triplet energy gap in fully conjugatedpolymers, using a donor-orthogonal acceptor motif to spatially separate electron and hole wave functions. This new generation of conjugatedpolymers allows for a greatly reduced exchange energy, enhancing triplet formation and enabling thermallyactivateddelayedfluorescence. We find that the mechanisms of both processes are driven
