Abstract
We report the synthesis and characterization of four novel CCC—NHC pincer platinum(II) and palladium(II) complexes, which adopt a distorted square planar configuration. These complexes emit bright blue light in the solid state under UV irradiation with emissions that are stable in ambient atmosphere (O 2 and H 2 O) for extended periods. We also report the synthesis and characterization of CCC—NHC pincer ligand nickel complexes, and solid state fluorescence spectra have been collected for two of the complexes reported. X-ray structural analysis of a representative compound exhibits a distorted square planar geometry. Finally, we report the synthesis and characterization of CCC—NHC pincer ligand complexes for abnormal carbenes, triazole, and BIA.
