Description	The electronic absorption and luminescence properties of electron-rich organometallic platinum(II) complexes with aromatic .alpha.-diimine ligands [(.alpha.-diimine)PtR2] (R = alkyl, alkynyl, Ph or Mes, Mes = 2,4,6-trimethylphenyl) were examined. The crystal and molecular structures of [(bpy)PtMe2], [(tap)PtPh2] and [(tmphen)PtMes2] were determined from single-crystal XRD and discussed in view of intermolecular interactions that influence the emission behaviour. The combination of theoretical calculations (DFT) and spectroscopic techniques (absorption and emission) revealed the character of electronic transitions and excited states. In particular they showed that the co-ligand involvement in the frontier orbitals is small for R = Me, but large in case of R = alkynyl, Ph or Mes. Depending on the chelate ligand and its substitution pattern, the emission efficiencies of the complexes cover a wide range from strong emission in fluid solution at ambient temperature.
