Synthesis, mesomorphism and luminescence properties of palladium(II) and platinum(II) complexes with dimeric Schiff base liquid crystals
摘要:
A series of ortho-metallated Pd and Pt complexes containing dimeric liquid crystals Schiff base as cyclo-metallated ligands and N-benzoyl thiourea derivatives as co-ligands were prepared and investigated for their liquid crystalline properties. Their structures were assigned based on elemental analysis, IR and H-1 NMR spectroscopy while the mesogenic properties were investigated by DSC and polarising optical microscopy. The complexes show either monotropic or enantiotropic transitions with nematic and smectic A phases being displayed, with the mesomorphic behaviour strongly related to the type of N-benzoyl thiourea as well as the metal center used. The structure of a palladium(II) complex has been solved by Xray diffraction.The platinum(II) complexes show photoluminescence properties both in solution and in solid state at room temperature, with the emission band centered around 600 nm. These are the first examples of metallomesogens based on Schiff base cyclometallated ligands that display luminescence properties. (C) 2009 Elsevier B. V. All rights reserved.
