Abstract: Abstract of thesis entitled DESIGN AND SYNTHESIS OF LUMINESCENT METAL POLYPYRIDYL COMPLEXES OF PLATINUM(II), RUTHENIUM(II) AND OSMIUM(II) FOR CHEMOSENSING AND BIOLOGICAL STUDIES Submitted by TANG WING SUEN for the degree of Doctor of Philosophy at The University of Hong Kong in November 2006 A series of platinum(II) terpyridyl alkynyl complexes derivatized with basic amino functionalities and crown ether pendants, [Pt(trpy)(C≡C-R)]X (R = - - -C H -N(CH ) -4, X = OTf; R = -C H -N(CH CH OCH ) -4, X = OTf; R = 6 4 3 2 6 4 2 2 3 2 - - -C H -NH-4, X = OTf; R = -C H -N(CH )-4, X = Cl; R = 6 4 2 6 4 3 2 - - -C H -N(CH CH OCH ) -4, X = Cl; R = -C H -NH -4, X = Cl; R = -B15C5, X 6 4 2 2 3 2 6 4 2 - - = OTf; R = -A15C5, X = OTf ) have been synthesized. The X-ray crystal structure of [Pt(trpy){C≡CC H -N(CH CH OCH )-4}](OTf) has been 6 4 2 2 3 2 determined. The lowest energy absorption of the complexes except [Pt(trpy)(C≡CB15C5)](OTf) were tentatively assigned to originate from a π(C≡C) → π*(trpy) ligand-to-ligand charge transfer (LLCT) transition mixed with some metal-to-ligand charge transfer (MLCT) contribution. The ion-binding and pH dependent properties have also been studied. Their photophysical and spectroscopic properties were shown to be dependent on pH and selected metal ions, and their colorimetric and luminescence chemosensing properties were described. Another series of platinum(II) terpyridyl alkynyl complexes, t - [Pt( Bu trpy)(C≡C-R)]X [R = -C H -NH -4, X = OTf; R = -C H -NCS-4, X = 3 6 4 2 6 4 - - - OTf; R =-C H -NHCOCH I-4, X = OTf; R = -UH-5 (UH = Uracil), X = Cl; 6 4 2 -UMe-5, X = OTf (UMe = 1,3-dimethyluracil)] have been successfully synthesized and characterized. The X-ray crystal structures of t t [Pt( Bu trpy)(C≡C-C H-NCS-4)](OTf), [Pt( Bu trpy)(C≡C-UH-5)]Cl and 3 6 4 3 [Pt( Bu trpy)(C≡C-UMe-5)](OTf) have been determined. Their photophysical and electrochemical behaviour, together with their protein labeling and DNA binding studies, have also been studied. The emission of the complexes in solution at room temperature has been tentatively assigned as originated from a dπ(Pt) → π*( Bu trpy) triplet MLCT excited state. The 77 K butyronitrile glass displayed dual luminescence which were assigned to originate from an intraligand (IL) phosphorescence of the terpyridine ligand and a dπ(Pt) → t 3 t π*( Bu trpy) MLCT phosphorescence. The [Pt( Bu trpy)(C≡C- 3 3 C H-NHCSNH-4)](OTf)-HSA and [Pt( Bu trpy)(C≡C-C H -NHCOCH S- 6 4 3 6 4 2 4)](OTf)-HSA (HSA = human serum albumin) bioconjugates were highly colored and exhibited luminescence in the visible region upon photoexcitation.

Iridium(III) in Optoelectronic and Photonics Applications
Author: Eli Zysman-Colman
Publisher: John Wiley & Sons
ISBN: 1119007151
Category : Science
Languages : en
Pages : 736
Book Description
The fundamental photophysical properties of iridium(III) materials make this class of materials the pre-eminent transition metal complex for use in optoelectronic applications. Iridium(III) in Optoelectronic and Photonics Applications represents the definitive account of photoactive iridium complexes and their use across a wide variety of applications. This two-volume set begins with an overview of the synthesis of these complexes and discusses their photophysical properties. The text highlights not only mononuclear complexes but also the properties of multinuclear and polymeric iridium-based materials and the assembly of iridium complexes into larger supramolecular architectures such as MOFs and soft materials. Chapters devoted to the use of these iridium-based materials in diverse optoelectronic applications follow, including: electroluminescent devices such as organic light emitting diodes (OLEDs) and light-emitting electrochemical cells (LEECs); electrochemiluminescence (ECL); bioimaging; sensing; light harvesting in the context of solar cell applications; in photoredox catalysis and as components for solar fuels. Although primarily targeting a chemistry audience, the wide applicability of these compounds transcends traditional disciplines, making this text also of use to physicists, materials scientists or biologists who have interests in these areas.

Book Description
Bioinorganic photochemistry is a rapidly evolving field integrating inorganic photochemistry with biological, medical and environmental sciences. The interactions of light with inorganic species in natural systems, and the applications in artificial systems of medical or environmental importance, form the basis of this challenging inter-disciplinary research area. Bioinorganic Photochemistry provides a comprehensive overview of the concepts and reactions fundamental to the field, illustrating important applications in biological, medical and environmental sciences. Topics covered include: Cosmic and environmental photochemistry Photochemistry of biologically relevant nanoassemblies Molecular aspects of photosynthesis Photoinduced electron transfer in biosystems Modern therapeutic strategies in photomedicine The book concludes with an outlook for the future of environmental protection, discussing emerging techniques in the field of pollution abatement, and the potential for bioinorganic photochemistry as a pathway to developing cheap, environmentally friendly sources of energy. Written as an authoritative guide for researchers involved in the development of bioinorganic photochemical processes, Bioinorganic Photochemistry is also accessible to scientists new to the field, and will be a key reference source for advanced courses in inorganic, and bioinorganic chemistry.

Languages : en
Pages : 247
Book Description
This book focuses on the latest fluorescent materials for cell imaging. Cell imaging is a widely used basic technique that helps scientists gain a better understanding of biological functions through studies of cellular structure and dynamics. In the past decades, the development of a variety of new fluorescent materials has significantly extended the applications of cellular imaging techniques. This book presents recently developed fluorescent materials, including semiconductor quantum dots, carbon dots, silicon nanoparticles, metal nanoclusters, upconversion nanoparticles, conjugated polymers/polymer dots, aggregation-induced emission (AIE) probes, and coordination compounds, used for various cellular imaging purposes. It will appeal to cell biologists and other researchers in academia, industry and clinical settings who are interested in the technical development and advanced applications of fluorescence imaging in cells, tissues and organisms to explore the mechanisms of biological functions and diseases.
