ABSTRACT: My research presents the results of an investigation into the photophysical properties of organometallic materials that contain platinum and iridium. Characterizing the excited-state properties of these types of compounds is necessary for a complete understanding of the materials which may have application in opto-electronics, as molecular wires, or as nonlinear optical materials, as well as help satisfy the need to gain insight into the fundamental nature of triplet excited states of conjugated organic systems. First, in order to partially characterize the excited states of these materials, a transient absorption apparatus was designed and constructed. Second, a series of platinum-containing molecules with two platinum atoms and different end groups were studied to examine interrupted conjugation through metal centers. Third, long carbon chains end-capped with platinum atoms were analyzed to determine the relationship between chain length and nonradiative decay rates. Lastly, an iridium complex with a known two-photon-absorbing ligand was studied to determine if excited-state absorption could be achieved through an initial multi-photon absorption process, and consequently exhibit nonlinear optical properties. The goal of this work was to further the understanding of triplet excited states in organometallic systems. The most important conclusions of this study are as follows: (i) the triplet excited states of small dinuclear platinum acetylides are more localized than the singlet excited states, and have disrupted conjugation through the platinum atom; (ii) long carbon chains display correlation to the energy gap law; (iii) the triplet excited state can be populated through two-photon absorption, which leads to nonlinear optical effects through enhanced dual-mechanism absorption.

Presents the state of the technology, from fundamentals to new materials and applications Today's electronic devices, computers, solar cells, printing, imaging, copying, and recording technology, to name a few, all owe a debt to our growing understanding of the photophysics and photochemistry of polymeric materials. This book draws together, analyzes, and presents our current understanding of polymer photochemistry and photophysics. In addition to exploring materials, mechanisms, processes, and properties, the handbook also highlights the latest applications in the field and points to new developments on the horizon. Photochemistry and Photophysics of Polymer Materials is divided into seventeen chapters, including: Optical and luminescent properties and applications of metal complex-based polymers Photoinitiators for free radical polymerization reactions Photovoltaic polymer materials Photoimaging and lithographic processes in polymers Photostabilization of polymer materials Photodegradation processes in polymeric materials Each chapter, written by one or more leading experts and pioneers in the field, incorporates all the latest findings and developments as well as the authors' own personal insights and perspectives. References guide readers to the literature for further investigation of individual topics. Together, the contributions represent a series of major developments in the polymer world in which light and its energy have been put to valuable use. Not only does this reference capture our current state of knowledge, but it also provides the foundation for new research and the development of new materials and new applications.

Aryl group can indeed be transferred into platinum metal having strong phosphine ligand provided that Cu(I) salts used as catalyst. Different ligands were tested to investigate the scope of the reaction, a library of monosubstituted, symmetrically disubstituted and asymmetrically disubstituted platinum complexes were prepared. Basic photophysical properties i.e. ground-state absorption, steady-state emission in both air-saturated and argon purged solutions were studied. Finally, the novel carbon-platinum bond formation reaction was used to synthesize a series of platinum complexes in which 2,1,3-benzothiadiazole was ligated with various electron-rich systems was connected via platinum metal. Extensive photophysical and electrochemical investigation was conducted on these novel platinum complexes.

This book presents a critical perspective of the applications of organometallic compounds (including those with metal or metalloid elements) and other related metal complexes as versatile functional materials in the transformation of light into electricity (solar energy conversion) and electricity into light (light generation in light emitting diode), in the reduction of carbon dioxide to useful chemicals, as well as in the safe and efficient production and utilization of hydrogen, which serves as an energy storage medium (i.e. energy carrier). This book focuses on recent research developments in these emerging areas, with an emphasis on fundamental concepts and current applications of functional organometallic complexes and related metal-based molecules for energy research. With contributions from front-line researchers in the field from academia and industry, this timely book provides a valuable contribution to the scientific community in the field of energy science related to metal-based molecular materials. Wai-Yeung Wong, PhD, is Chair Professor and Head of the Department of Chemistry at Hong Kong Baptist University, Hong Kong, P. R. China.
