Abstract: Abstract of thesis entitled SYNTHESES, CHARACTERIZATION AND PHOTOPHYSICAL PROPERTIES OF PLATINUM(II) AND GOLD(I) COMPLEXES CONTAINING ORTHO- AND META- OLIGO(PHENYLENEETHYNYLENE) LIGANDS Submitted by Zhu Mingxin for the degree of Doctor of Philosophy at The University of Hong Kong in March 2008 Metal complexes containing oligo(phenyleneethynylene) (PE) are of great importance in photophysics and material science. The syntheses, characterizations and photophysical properties of the light-emitting platinum(II) and gold(I) complexes with flexible ortho- and meta-PE and 2,5-diphenyl-1,3,4-oxadiazole ligands were described. Several novel dinuclear terpyridyl platinum(II) complexes with ortho-PE ligands were synthesized and their crystal structures were determined. The t t 2+ t platinum(II) complexes [( Bu tpy)Pt-(ortho-PE)-Pt( Bu tpy)] ( Bu tpy = 4,4′,4″-tri- 3 3 3 tert-butyl-2,2′ 6′,2″-terpyridine) adopted a helical conformation in their crystal structures, and their phosphorescence recorded in acetonitrile/water mixtures shifted to lower energy with enhanced intensity when the water content increased. A hydrophobic folding process was suggested for the complexes with long ortho-PE(n) (n >= 3), and the red-shifted and enhanced phosphorescence was attributed to inter- and intra-molecular π-π interactions. The mononuclear terpyridine and C DEGREESN DEGREESN capped t + platinum(II) complexes [( Bu tpy)Pt-(ortho-PE)] and [(C DEGREESN DEGREESN)Pt-(ortho-PE)] (HC DEGREESN DEGREESN = 6-phenyl-2,2′-bipyridine) were studied for comparison. A series of mononuclear and dinuclear ortho- and meta-PE gold(I) complexes, [(PCy )Au-(ortho-PE)] (PCy = tricyclohexylphosphine), [(PCy )Au-(ortho-PE)- 3 3 3 Au(PCy)], [(PCy )Au-(meta-PE)] and [(PCy )Au-(meta-PE)-Au(PCy)] were 3 3 3 3 synthesized to examine the effect of ortho- and meta-conjugation. A ππ* emission of the PE ligands was switched on at room temperature by the attachment of [Au(PCy )] fragment due to the heavy atom effect. The delayed fluorescence from the ππ* excited states of the PE ligands was observed, and a triplet-triplet annihilation pathway was proposed. The difference in conjugation of para-, ortho- and meta-PE ligation was examined by comparison of the singlet and triplet emission energies of the gold(I) complexes. By extrapolating the plot of the emission energy against the PE chain length in the complex, the triplet emission energies of poly(ortho-PE) and poly(meta-PE) were estimated to be 530 and 470 nm respectively. These complexes together with the reported [Au(PCy )] complexes containing para-PE ligands, constitute a complete class of [Au(PCy )] supported phenyleneethynylene complexes. 2+ New ortho-PE ligands were used as flexible linkers for [Pt(PEt ) ] moieties 3 2 (PEt = triethylphosphine). Three neutral platinum(II) macrocycles with the maximum ring size of 60 atoms were synthesized and their crystal structures were determined, 31 revealing decreased nuclearity when the ortho-PE length increases. The P NMR spectra of [Pt(PEt ) {ortho-PE(5)}] with a rigid conformation at various temperatures 3 2 are consistent with the calculated spectrum of ABX spin system. A series of platinum(II)-bis(triethylphosphine) complexes containing 2,5- diphenyl-1,3,4-oxadiazole moiety were synthesized, and

Book Exploring the Bonding and Reaction Chemistry of Gold and Platinum Complexes

Download or read book Exploring the Bonding and Reaction Chemistry of Gold and Platinum Complexes written by Bruce Wayne Flint and published by . This book was released on 2001 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Platinum complexes have been synthesized and characterized. Relative Pt-X Bond Dissociation Energies (BDE's) for these complexes have been calculated from experimentally measured equilibrium and organic BDE's. Changes in relative BDE's are noted when ligands for the complexes are exchanged. Oxygen atom transfer reactions by a new platinum hydroxo catalyst have been studied. This catalyst is generated by the reaction of a platinum oxo complex with water and catalytically activates the reaction of the this complex with ethylene. The kinetics of this reaction have been studied and a reaction pathway has been proposed. The synthesis and characterization of a series of heteroatom substituted gold imido complexes have been reported. It has been demonstrated that the stability of gold imido complexes has a linear free energy relationship with the donor strength of the adjacent phosphine ligand. The decomposition of the complex involves the release of a free nitrene. Larger phosphine ligands retard the decomposition, and the decomposition is blocked by alkylation of the hydrazido ligand.

Available in PDF, EPUB and Kindle. Book excerpt: The results are reported of research which was undertaken (1) to determine the chemical shifts of cis and trans isomers of platinum(II) complexes in hope of gaining information about pi-bonding in the Pt-P bond, and to extend this study to palladium(II); (2) to determine trends which may exist within a series of ligands for the purpose of developing expressions that would enable calculation of chemical shifts for complexes; (3) to expand the knowledge of the chemistry of tertiary phosphine complexes of platinum(II) and palladium(II); and (4) to determine phosphorus-phosphorus coupling constants by preparing a complex of a chelating diphosphine (R2PCH2CH2PR'2) or by preparing a complex containing two different phosphines.
