Spectral and photophysical properties of mono and dinuclear Pt(II) and Pd(II) complexes: An unusual emission behaviour
Mononuclear complexes of the formula [M(N-N)(DHB)] and dinuclear complexes of the formula [M2(BPY)2(THB)] were synthesized and characterized. These complexes were found to show an optically active LLCT band and the platinum complexes of the series were found to show dual emitting states. Eight mononuclear complexes of the formula [M(N-N)(DHB)] and two binuclear complexes of the formula [M2(BPY)2(THB)] {where M = Pd(II) or Pt(II), N-N = 2,2?-bipyridine (BPY), 2,2?-biquinoline (BIQ), 4,7-diphenyl-1,10-phenanthroline (DPP), 1,10-phenanthroline (PHEN); DHB = dianion of 3,4-dihydroxybenzaldehyde and THB = tetraanion of 3,3?,4,4?-tetrahydroxy benzaldazine} were prepared and their electrochemical, spectral and photophysical properties were examined. These complexes were characterized by chemical analysis, IR and proton NMR spectroscopy. A detailed study on the absorption spectroscopy of these complexes was made. These complexes were found to show a low-energy solvatochromic ligand-to-ligand charge-transfer (LLCT) band. The electronic energies of these bands have been analyzed and compared with electrochemical data. Emission behaviour of the complexes of the series, [Pt(N-N)(DHB)], [Pt(N-N)(DHBA)] {where DHBA is the dianion of 3,4-dihydroxybenzoic acid} and [Pt2(BPY) 2(THB)] was also investigated. These platinum complexes were found to emit from a low-energy state at low temperature and a high-energy state at room temperature. Photophysics of these complexes is also discussed.
