This book was released on 2012 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyclometalated Ir(III) and Pt(II) compounds are among the most promising phosphorescent emitters for various applications, such as organic light emitting diodes (OLEDs), chemical sensors and bioimaging labels. This family of complexes exhibits high thermal and photo-stability, excellent quantum efficiency, and relatively short lifetime. More importantly, their luminescent properties can be fully tunable by modifying the coordinating ligands. In this thesis, a series of 2-(1,2,3-triazol-4-yl)-pyridine derivatives, referred to as the "click" ligands, are used to build phosphorescent Ir(III) and Pt(II) compounds. The robust and tolerant nature of the copper mediated 1,3-dipolar cycloaddition reactions offers great flexibility in the molecular design. Chapter 1 and Chapter 2 focus on the synthesis of heteroleptic cyclometalated Ir (III) and Pt(II) complexes by utilizing the Cu(I) triazolide intermediates generated in "click" reactions as transmetalating reagents. Ligand synthesis and metalation can be achieved in one pot under mild reaction conditions. For the Ir(III) system, the "click" ligands show switchable coordination modes, between the C, N- and N, N-chelation. These ligands act as C, N, N-bridging units to form unique zwitterionic dinuclear complexes with two cyclometalated Pt(II) units. In Chapter 3, cyclometalated Pt(II) complexes with N, N-chelating "click" ligands are synthesized. Their aggregation-induced solid-state emission is highly responsive to environmental stimuli, such as solvents, heat and mechanical force. This family of compounds represents the first thermotropic Col(h) liquid crystals with only one sidechain. Furthermore, the combined liquid crystalline and mechanochromic properties make them attractive functional materials.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book reports the basics of hybrid phosphor materials, their synthesis routes and their special properties and characterization techniques. It gives the reader information about the natural origins and development of hybrid materials, which are developed by combining inorganic and organic species in one material interface-determined materials. The book provides a general classification of hybrid materials, wherein inorganic materials modified by organic moieties are distinguished from organic materials or matrices modified by inorganic constituents. It gives a focus to the functionalization of organic materials by inorganic additives. The application areas covered include optoelectronic field, sensor applications, biological and environmental applications.

Available in PDF, EPUB and Kindle. Book excerpt: The development of phosphorescent materials is mainly driven by their prospective applications in a broad range of fields such as chemistry, biological science and biomedicine, and optoelectronic technologies. This primer is structured to introduce you to the fascinating field of phosphorescent materials, covering fundamental concepts of photophysics, basic characterization of phosphorescent materials, types of phosphorescent materials, and applications. It should be emphasized that the discussion on phosphorescent materials is far from comprehensive; rather it highlights the design strategies, structural types, and important features of the materials. Readers are referred to the “Read These Next” for expanded coverage and cited references including original research articles and review papers for further information. Research in phosphorescent materials is highly collaborative as it stretches into various disciplines including not only chemistry but also biology, physics, and engineering. Therefore, this primer also serves as a bridge to other fields that may be of interest

Book excerpt: 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.
