A library of 1,2- cyclometalated Pt(II) complexes based on various bidentate N,C-chelate chromophores have been studied for their uses as luminescent oxygen sensing probes (OSPs). The bidentate chelate ligands have been found to have a distinct impact on the performance of the Pt(II) compounds as OSPs. For some of the complexes, attachment of a dimesityl boron group (BMes2) to the chelate ligands enhances their oxygen sensitivity. For phenyl-1,2,3-triazole (Phtrz) based Pt(II) complexes, the attachment of a diphenyl amino moiety to the N,C-chelate ligand substantially enhances phosphorescence quenching and the performance of the OSP. A high kSVapp value (0.0667 Torr−1) for the OSP based on the diphenyl amino functionalized Pt(II) complex was achieved, which is the highest value reported to date for OSPs based on bidentate Pt(II) complexes.
