Available in PDF, EPUB and Kindle. Book excerpt: The chemistry of platinum group metals is a rapidly expanding commercially important field. It is dominated by the catalytic properties of the metals. They are useful in petrochemical and general chemical plants and are becoming increasingly important as autocatalysts for pollution control. The book covers recent developments in the chemistry of the six platinum group metals, namely, platinum, palladium, rhodium, iridium, ruthenium and osmium. The material falls into three broad areas. Firstly, the occurrence, extraction and use of the metals, especially in catalysis, electrochemistry, energy and electronics. Secondly, organometallic and homogeneous catalytic chemistry and last but not least coordination chemistry including biochemistry and cancer therapy. The work is aimed at scientists in universities and in industry using any of the six platinum group metals in research. It will be useful for those studying the compounds of the metals themselves, and those considering to use either the metals or their complexes and catalysts in their experimental work.

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

Abstract: Abstract of thesis entitled LUMINESCENT PLATINUM(II) COMPLEXES CONTAINING DIANIONIC TETRADENTATE LIGANDS HAVING MIXED OXYGEN, NITROGEN AND CARBON DONOR ATOMS AND PLATINUM(II)-CONTAINING PHOSPHORESCENT POLYMERS: SYNTHESIS, PHOTOPHYSICAL PROPERTIES AND MATERIAL APPLICATIONS Submitted by TONG WAI YIP for the degree of Doctor of Philosophy at The University of Hong Kong in May 2014 Square planar platinum(II) complexes exhibit rich photophysical properties which are tunable through the structural variation of ligands and can be harnessed for applications in materials science. In this thesis, the great variety of spectroscopic properties of various square planar cyclometalated platinum(II) complexes supported by tetradentate (O DEGREESN DEGREESN DEGREESC and O DEGREESN DEGREESC DEGREESN) and tridentate (C DEGREESN DEGREESN) ligands containing dipyridyl moieties will be highlighted, along with their synthesis, characterization and potential application in organic light emitting diodes (OLEDs). Ind Platinum(II) complexes supported by tetradentate O DEGREESN DEGREESN DEGREESC or O DEGREESN DEGREESN DEGREESC types of ligands (O DEGREESN DEGREESN DEGREESC = 2-(4-(3,5-di-tert-butylphenyl)-6'-phenyl-2,2'- Ind bipyridin-6-yl)phenolate; O DEGREESN DEGREESN DEGREESC = 5,5-dialkyl-2-(6-phenylpyridin-2-yl) indeno[1,2-b]pyridin-9-olate) are emissive in solution at room temperature, with emission maxima tunable from 582 nm to 640 nm and quantum yields up to 0.28. Mechanochromism and the associated luminescence change in [Pt(dihexyl- Ind O DEGREESN DEGREESN DEGREESC)] (Complex 3.6) were found associated with the two different crystal packings revealed by powder X-ray diffraction (PXRD) studies. Fast vapochromic response of [Pt(3-O DEGREESN DEGREESN-2,6-difluoropyridine)] (Complex 3.3) on chloroform or dichloromethane vapours was found to be associated with structural changes in the solid state through PXRD studies. Robust and strongly emissive platinum(II) complexes supported by tetradentate O DEGREESN DEGREESC DEGREESN ligands featuring fused six-five-six membered metallacyclic ring (O DEGREESN DEGREESC DEGREESN = 2-(4-(3,5-di-tert-butylphenyl)-6-(9-(pyridin-2-yl) carbazol-2-yl)pyridin-2-yl)phenol) have been prepared. These platinum(II) complexes are among the most efficient yellow phosphors, with emission maxima ranging from 526 nm to 553 nm and luminescence quantum yields as high as -1 0.47-0.86. A yellow OLED with power efficiency (η ) up to 52 lm W is power demonstrated. In combination with the typical blue emitting iridium(III) 2' bis(4,6-difluorophenyl-pyridinato-N, C ) picolinate (FIrpic), white organic -1 light-emitting diodes (WOLEDs) displayed η up to 61 lm W and reduced power -2 efficiency roll-off at 1000 cd m . Random copolymers with photo-inert backbone poly[(N-vinylcarbazole)-co- ((R-C DEGREESN DEGREESN)Pt)] and poly[(2-(4-tert-butylphenyl)-5-(4-vinylphenyl)-1,3,4- oxadiazole)-co-((R-C DEGREESN DEGREESN)Pt)] (R-C DEGREESN DEGREESN = 3-(6-phenyl-4-(4-vinylphenyl) pyridine-2-yl)-isoquinoline or 3-(4-(4-(dec-9-enyloxy)phenyl)-6-phenylpyridin- 2-yl)isoquinoline) have been synthesized and characterized. Energy transfer between the charge transporting units and emissive (R-C DEGREESN DEGREESN)Pt units was revealed through ICP-MS inve

Abstract: Several cyclometalated Pt(II) isocyanide complexes containing C-deprotonated C DEGREESN DEGREESC ligands (C DEGREESN DEGREESC = 2,6-diphenylpyridine derivatives) were synthesized. These complexes display orange-red emissions with max at 582-619 nm and quantum yields of up to 26% in CH2Cl2 at room temperature. The incorporation of carbazole/fluorene/thiophene unit(s) to C DEGREESN DEGREESC ligands leads to minimized structural distortion of complexes in their excited states and thereby suppresses non-radiative decay pathways. The high thermal stability (Td >300 C) renders these complexes good candidates as phosphorescent dopants in organic light-emitting diodes (OLEDs). Red-emitting OLEDs with CIE coordinates of (0.650.01, 0.350.01) were fabricated by vacuum deposition, showing a maximum external efficiency of 12%. In addition, well-defined nano/microstructures were obtained from self-assembly of these complexes driven by π∙∙∙π, C-H∙∙∙π and C-H∙∙∙H-C interactions as observed in the crystal structures. Two series of organopalladium(II) alkynyl complexes containing a terpy (terpy = 2,2':6',2''-terpyridine) or C DEGREESN DEGREESC pincer carbene ligand (C DEGREESN DEGREESC = 2,6-bis(1-butylimidazol-2-ylidenyl)pyridine) were prepared. These complexes are non-emissive in solution at room temperature except that the one containing both C DEGREESN DEGREESC and pyrenylacetylide ligands shows phosphorescence (Φ = 0.3%) originating from intraligand state of the acetylide ligand. This could be attributed to the strong -donating N-heterocyclic carbene (NHC) in the pincer ligand that strongly destabilizes d-d state, the population of which provides an efficient non-radiative decay channel. To make comparison between Pd(II) and Pt(II) complexes with the two ligand systems, Pt(II) C DEGREESN DEGREESC alkynyl complexes were also prepared. They are emissive in solution and some display excimer emissions at high concentration (〖10〗 DEGREES(-4)-〖10〗 DEGREES(-3) mol 〖10dm〗 DEGREES(-3)). The X-ray crystal structures of [Pd(L)(CCPh)](〖PF〗_6) (L = terpy and C DEGREESN DEGREESC) revealed one-dimensional chain stacking of complex cations with alternating Pd(II)∙∙∙Pd(II) contacts of about 3.29-3.35 A and π-π interactions of about 3.4 A . Well-defined submicron/nanostructures were obtained from self-assembly of Pd(II) and Pt(II) alkynyl complexes driven by π-π interactions between aromatic moieties and/or metal∙∙∙metal interactions. DFT calculations on the optimized structures of [M(L)(CCPh)]+ (M = Pd(II) and Pt(II)) revealed the existence of metal∙∙∙metal closed-shell interactions. In addition, the complex containing the C DEGREESN DEGREESC ligand exhibits slightly enhanced metal∙∙∙metal interactions and larger "bonding" energy upon dimerization. Furthermore, spin-orbit coupling between singlet and triplet excited states is more effective which promotes rapid intersystem crossing. A new class of cyclometalated Au(III) complexes containing C-deprotonated C DEGREESN ligands (C DEGREESN = 2-phenylpyridine and its derivatives) and cis-chelating bis-NHC ligands was synthesized. These are the first examples of Au(III) complexes supported by cis-chelating bis-NHC ligands. They display emissions in solution under degassed condition at room temperature with &
