Abstract: Abstract of thesis entitled "SYNTHESES AND PHOTOPHYSICS OF LUMINESCENT MONO- AND DINUCLEAR RHENIUM COMPLEXES CONTAINING FUNCTIONAL LIGANDS" Submitted by Wong Man Chung for the degree of Doctor of Philosophy at The University of Hong Kong ABSTRACT With the growing interest in the exploration of inorganic/ organometallic sensing materials, a series of mononuclear rhenium(I) and rhenium(V) and dinuclear rhenium(I) (DIC-18-C-6)Cl], complexes with crown ether pendants of formula [Re(CO) [{Re(CO) Cl}(DDIC)], [Re(CO)(DIC-S)Cl], [Re(CO)(DIC-3S)Cl], [Re(CO) (DIC- 3 2 3 3 3 Se)Cl], [Re(CO) (DPPZC)Cl] and [Re (PPh ) (C≡C-benzo-15-crown-5) ] have been 3 3 2 2 synthesized. The photophysical, electrochemical and cation-binding properties of these systems have been studied. The structure of [Re(CO) (DIC-Se)Cl] has been established by X-ray crystallography. The electronic absorption energies of the rhenium(I) complexes were found to be sensitive to the presence of metal cations. The stability constants of [Re(CO)(DIC-18-C-6)Cl] and [{Re(CO) Cl}(DDIC)] for alkali and 3 3 2 alkaline-earth metal cations have been determined by UV-visible spectrophotometry. The complexes [Re(CO)(DIC-S)Cl], [Re(CO)(DIC-3S)Cl] and [Re(CO) (DIC-Se)Cl] 3 3 3 showed a downfield shift of methylene protons adjacent to the sulphur or selenium atom on the crown ether moiety upon addition of silver ion in deuterated acetonitrile. Their stability constants for silver ion have also been determined by UV-visible and H NMR spectroscopies. Direct evidences for the formation of the inclusion species between the crown ether-containing rhenium(V) complex [Re (PPh ) (C≡C-benzo-15-crown-5) ] and 3 2 2 lithium or sodium ions were obtained from electrospray ionization-mass spectrometry. A series of mononuclear and dinuclear rhenium(I) complexes with thiolate and selenolate ligands, [Re(CO) (N-N)(S-C H -X-p)] and [{Re(CO) (N-N)} (μ-S-C H -X- 3 6 4 3 2 6 4] t p)], have been synthesized (N-N = bpy, Me -bpy, Bu -bpy, phen; X = CH, OCH, 2 2 3 3 C(CH ), Cl, F). Unsymmetrical dinuclear rhenium(I) thiolate complexes have been 3 3 prepared by utilizing the mononuclear complexes as precursors. Their electrochemical properties have also been studied. The photophysical behaviour of the dinuclear complexes has been studied. Attempts to investigate the photophysical behaviour of the mononuclear counterparts were unsuccessful owing to their low photo-stability. The crystal structures of the complexes [Re(CO) (phen)(SC H -OCH -p)], [Re(CO) ( Bu - 3 6 4 3 3 2 bpy)(SePh)], [{Re(CO) (bpy)} (μ-SC H -CH -p)]OTf, [Re(CO) (phen)(μ-SC H -OMe- 3 2 6 4 3 3 6 4 p)Re(CO) (bpy)]OTf and [Re(CO) (Me -bpy)(μ-SC H -Me-p)Re(CO) (NO -phen)]OTf 3 3 2 6 4 3 2 have also been determined. Besides, a series of luminescent rhenium(I) acetylide complexes with diimine ligands, [Re(CO) (N-N)(C≡C-R)] (N-N = bpy, Me -bpy, phen, NO -phen; R = Ph, C H - 3 2 2 6 4 Cl-p, C H -C H -p, C H -C≡CH-p, C H -N=N-C H -OC H, EEME), have been 6 4 8 17 6 4 6 4 6 4 12 25 synthesized and their photophysical and electrochemical properties studied. The X-ray crystal structure of [Re(CO) (bpy)(C≡C-Ph)] has been determined. An unsymmetrical dinuclear complex, [(bpy)(CO) Re-C≡C-C H -C≡C-C≡C-C H -C≡C-Re(CO) ( Bu -bpy)] 3 6 4 6 4 3 2 has been prepared by

This book was released on 2015-06-30 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors. Readership: research scientists at universities or in industry, graduate students Special offer For all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink.

Book excerpt: Photochemistry (a term that broadly speaking includes photophysics) is abranchofmodernsciencethatdealswiththeinteractionoflightwithmatter and lies at the crossroadsof chemistry, physics, and biology. However, before being a branch of modern science, photochemistry was (and still is today), an extremely important natural phenomenon. When God said: “Let there be light”, photochemistry began to operate, helping God to create the world as wenowknowit.Itislikelythatphotochemistrywasthesparkfortheoriginof life on Earth and played a fundamental role in the evolution of life. Through the photosynthetic process that takes place in green plants, photochemistry is responsible for the maintenance of all living organisms.

Photochemistry as a science is quite young; we only need to go back less than one century to ?nd its early pioneer [1]. The concept of coordination compound is also relatively young; it was established in 1892, when Alfred Werner conceived his theory of metal complexes [2]. Since then, the terms coordination compound and metal complex have been used as synonyms, even if in the last 30 years, coordination chemistry has extended its scope to the binding ofall kinds of substrates [3, 4].
