Abstract: Abstract of thesis entitled SYNTHESIS, CHARACTERIZATION, AND PHOTOPHYSICAL STUDIES OF ORGANIC- LANTHANIDE COMPLEXES Submitted by Ka-Leung Wong For Degree of Doctor of Philosophy at The University of Hong Kong in August 2006 The general background and coordination chemistry of lanthanides, their characteristic luminescent properties and nonlinear luminescent properties with the applications to material science and biological systems are reviewed. The design and synthesis of lanthanide-organic complexes based on similar tripodal amide ligands N-[2-(bis{2-[(ortho- substituent -benzoyl)amino]ethyl}amino)- ethyl]benzamide (ortho substituent-C H N O ) and bidentate amide ligands di-2- 27 27 4 3 methoxy-(2-aminoethyl)benzamide (C H N O ) were described. These ligands were 20 33 3 8 found to have different coordination to the lanthanide that caused a change in the photo-physical properties. The occurrences of high order multi-photon processes are rare, especially with lanthanide complexes. Generally there is a lack of clear molecular structure in systems that have been reported in the literature, hindering our understanding of the correlation of photo-structural properties. Our complexes have been found to display two different forms of coordination, which significantly affects their photo-properties. X-Ray structure analysis showed that, one being a linear polymeric form and the other a dendritic form, the latter has been found to exhibit an additive harmonic generation process as well as the multi-photon process which is present in both types of coordination. The design and synthesis of a metal-organic network were described based on a lanthanide complex that contains mucic acid, {[Ln(Mucicate) (H O) ].5H O} (Ln 1.5 2 2 2 n = Eu and Tb), exhibiting a novel 1-D hydrophilic channel in the porous framework. The 3D framework with a hydrophilic inner surface was found to exhibit a reversible - - - - anion uptake. Upon addition of an aqueous solution of sodium salts of I, Br, Cl, CN, 2- CO, to a solid sample of the Ln complex, the luminescent intensity enhancements were observed. The anion response of the channels is believed to be due to the effect of numerous OH groups in the mucic acid, which interacts strongly with the anion through hydrogen bonding. Experimental details including instruments used for physical characterization and the photo-physical measurement for linear, multi-photon absorption induced f-f emission and nonlinear emission were presented.

Available in PDF, EPUB and Kindle. Book excerpt: Lanthanide elements were first used some thirty years ago in the optical glass industry, followed shortly by their use as NMR shift reagents in organic chemistry. Since then, the application of lanthanides in studies of organic and biochemical systems by use of their NMR and spectroscopic properties has created a rapidly growing interest in the physics and chemistry of these elements. Their use in industrial catalysts, electronic and optical components, high-temperature superconductors, in medicine as X-ray intensifying materials, relaxation agents for imaging techniques or radioisotopes for pharmaceutical applications, have combined with their utilisation in science as probes of a wide variety of phenomena giving them a prominent place in modern science. In this book, leading experts describe the various facets of the application of lanthanides as probes in life, chemical and earth sciences. The aim is to provide guidance to scientists who may wish to use the unique advantages of lanthanide probes in their own fields.To supplement the chapters on the basic concepts of the application of lanthanides, chapters are provided on the basic chemistry of these elements and on the synthetic and analytical aspects of lanthanides and their compounds. The book thus provides a great deal of useful information which will no doubt assist scientists in using these fascinating and valuable elements in their research.
