Luminescent alkynylplatinum(II) terpyridine-containing conjugated polymers: synthesis, characterization and photophysical studies

A series of alkynylplatinum(II) terpyridine complexes and terpyridine-containing conjugated polymers with different polymer backbones has been synthesized, their spectroscopic properties Förster resonance energy transfer (FRET) processes investigated. The platinum(II)-containing exhibit dual emissive features emission maxima at ca. 416-465 nm 671-673 nm, which are assigned to be originated from singlet intraligand (1IL) excited states the backbone triplet metal-metal-to-ligand charge (3MMLCT) platinum(II) pendants, respectively. radii (R0) have determined, distinctive thermo-responsive luminescence changes also observed. present work demonstrated utilization “click” reaction for preparation polymers, show unique photophysical properties. Through judicious design, this type is found sensitive temperature, resulting in ratiometric changes. This study provided valuable insights into metal-containing polymeric systems applications.
