Abstract: Abstract of thesis entitled DESIGN, SYNTHESIS AND FUNCTIONALIZATION OF LUMINESCENT ALKYNYLPLATINUM(II) COMPLEXES OF TRIDENTATE N-DONOR LIGANDS AS BUILDING BLOCKS FOR METALLOFOLDAMERS, SUPRAMOLECULAR ASSEMBLIES AND NANOSTRUCTURES submitted by LEUNG Yu Lut Sammual for the degree of Doctor of Philosophy at The University of Hong Kong in August 2013 A series of dinuclear platinum(II)-containing meta-phenylene ethynylene (mPE) oligomers and binaphthol derivatives of various lengths, end-capped with symmetric or unsymmetric platinum(II) terpyridine units has been synthesized and characterized. In addition, a mononuclear complex with five repeating mPE units has also been synthesized for comparison studies. Dinuclear alkynylplatinum(II) terpyridine complexes with the optimum length of meta-phenylene ethynylene (mPE) units and the binaphthol derivatives have been found to exhibit a strong tendency to fold back onto themselves to form short helical strands through the stabilization of Pt---Pt and interactions. The steric bulk of the terpyridine ligands and the length of the oligomeric bridge have been found to affect the extent of the intramolecular Pt---Pt interaction that governs the i stabilization of the short helical strand in solution. Their folding properties via Pt---Pt and stacking interactions have been studied by
