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 (O2 and H2O) 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.
