Abstract: A series of water-soluble platinum(II) terpyridine complexes with functionalized alkynyl ligands and a boronic acid-containing polymer, PAAPBA, have been synthesized and characterized. The photophysical and electrochemical properties of all the platinum(II) complexes have been studied. Some of the complexes have been demonstrated to show ground-state aggregation in organic solvents and aqueous solutions at high concentrations, leading to Pt...Pt and/or π-π interactions and hence the emergence of metal-metal-to-ligand charge transfer (MMLCT) transitions in both the UV-visible and emission spectra. The induced self-assembly of [Pt(tpy)(C≡CC6H4-CH2NMe3-4)](OTf)2 by PAAPBA has been explored for the development of glucose sensing protocols and α-glucosidase assay by monitoring the triplet metal-metal-to-ligand charge transfer (3MMLCT) emission in the near-infrared (NIR) region. [Pt(tpy){C≡CC6H4- {NHC(=NH2])(NH2)}-4}](OTf)2 has been observed to undergo induced aggregation in the presence of citrate, with good selectivity over other mono- and dicarboxylates in the tricarboxylic acid (TCA) cycle. Enzymatic activity of citrate lyase has also been probed by the emission spectral changes of the complex in the NIR region. A series of water-soluble alkynylplatinum(II) terpyridine complexes and water-soluble conjugated polyelectrolytes (CPEs) have been synthesized and characterized. The UV-vis absorption and emission properties of the platinum(II) complexes and CPEs have been investigated in organic solvents and/or aqueous buffer solutions. The electrochemical properties and ground-state aggregation at high concentrations of the platinum(II) complexes have also been examined. Two-component ensembles containing selected platinum(II) complexes and PPE-SO3- have been studied, and Forster resonance energy transfer (FRET) has been demonstrated from the PPE-SO3- donor to the aggregated complexes as acceptors. The ensemble containing PPE-SO3- and [Pt(tpy)(C≡CC6H4CH2NMe3-4)](OTf)2 has been employed for a "proof-of-principle" label-free detection of human serum albumin (HSA) in pH 3 buffer solutions with high selectivity and sensitivity, while another ensemble containing PPE-SO3- and [Pt{tpy(C6H4CH2NMe3-4)-4'}(C≡CC6H5)](OTf)2 has been utilized for selective label-free detection of G-quadruplex structure of the human telomeric DNA in physiological buffer solutions. A series of water-soluble platinum(II) terpyridine complexes with stimuli-responsive alkynyl ligands and a series of water-soluble platinum(II) metallosupramolecular triblock copolymers have been synthesized and characterized. The photophysical and electrochemical properties as well as the ground-state aggregation of the complexes have been investigated. Some of them have been found to show different electronic absorption and emission properties in aqueous solution at different pHs due to aggregation/deaggregation of the complexes. One of the complexes has been employed for live-cell imaging experiments to locate acidic organelles, such as lysosomes, in MDCK cells. The water-soluble platinum(II) metallosupramolecular triblock copolymers have been found to show an increase in 3MMLCT emission intensity in the red-NIR region with temperature, which has been attribu

Available in PDF, EPUB and Kindle. Book excerpt: A growing interest has been devoted to the development of host systems for ionic and neutral species based on calixarenes. These cyclic oligomers show important host-guest properties, which has led to numerous applications in a broad range of fields, including organocatalysis, sensing, extraction and separation, and, more recently, biomedical applications. The relative ease of the functionalization of their upper and lower rims and the presence of a pre-organized cavity that is available in different sizes and conformations make calixarenes attractive building blocks for the construction of supramolecular assemblies. This book presents the most recent developments on the host-guest properties of calixarenes, as well as the new synthetic methods and applications.

Download or read book Anion Receptor Chemistry written by Jonathan L Sessler and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anion recognition plays a critical role in a range of biological processes, and a variety of receptors and carriers can be found throughout the natural world. Chemists working in the area of supramolecular chemistry have created a range of anion receptors, drawing inspiration from nature as well as their own inventive processes. This book traces the origins of anion recognition chemistry as a unique sub-field in supramolecular chemistry while illustrating the basic approaches currently being used to effect receptor design. The combination of biological overview and summary of current synthetic approaches provides a coverage that is both comprehensive and comprehensible. First, the authors detail the key design motifs that have been used to generate synthetic receptors and which are likely to provide the basis for further developments. They also highlight briefly some of the features that are present in naturally occurring anion recognition and transport systems and summarise the applications of anion recognition chemistry. Providing as it does a detailed review for practitioners in the field and a concise introduction to the topic for newcomers, Anion Receptor Chemistry reflects the current state of the art. Fully referenced and illustrated in colour, it is a welcome addition to the literature.

Download or read book Metallo Supramolecular Polymers written by Masayoshi Higuchi and published by Springer Nature. This book was released on 2019-11-12 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the synthesis, electrochemical and photochemical properties, and device applications of metallo-supramolecular polymers, new kinds of polymers synthesized by the complexation of metal ions and organic ditopic ligands. Their electrochemical and photochemical properties are also interesting and much different from conventional organic polymers. The properties come from the electronic intra-chain interaction between the metal ions and the ligands in the polymer chain. In this book, for example, the electrochromism that the Fe(II)-based metallo-supramolecular polymer exhibits is described: the blue color of the polymer film disappears by the electrochemical oxidation of Fe(II) ions to Fe(III) and the colorless film becomes blue again by the electrochemical reduction of Fe(III) to Fe(II). The electrochromism is explained by the disappearance/appearance of the metal-to-ligand charge transfer absorption. The electrochromic properties are applicable to display devices such as electronic paper and smart windows.

Download or read book Selective Nanocatalysts and Nanoscience written by Adriano Zecchina and published by John Wiley & Sons. This book was released on 2011-09-19 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filling a gap in the catalysis and nano literature, this monograph is unique in focusing on both nanostructured heterogeneous and homogeneous catalysis. As such, it describes a selection of heterogeneous catalysts in use, showing that the dimension of the relevant portions of the catalysts are always in the 1-100 nm range, and so may be properly understood as nanomachines for the chemical manipulation of molecules to perform high precision selective synthesis. The prominent international authors then go on to show that the concept of nanoscience can be equally applied to artificial homogeneous catalysts whose active sites are generally considered as "single-sites" having a "molecular" dimension. The result is an excellent overview of such hot topics as nanoparticles, MOFs and more, making this indispensable reading for catalytic and organic chemists, as well as those working on organometallics.

Download or read book Introduction to X Ray Powder Diffractometry written by Ron Jenkins and published by Wiley-Interscience. This book was released on 1996-07-12 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: When bombarded with X-rays, solid materials produce distinct scattering patterns similar to fingerprints. X-ray powder diffraction is a technique used to fingerprint solid samples, which are then identified and cataloged for future use-much the way the FBI keeps fingerprints on file. The current database of some 70,000 material prints has been put to a broad range of uses, from the analysis of moon rocks to testing drugs for purity. Introduction to X-ray Powder Diffractometry fully updates the achievements in the field over the past fifteen years and provides a much-needed explanation of the state-of-the-art techniques involved in characterizing materials. It covers the latest instruments and methods, with an emphasis on the fundamentals of the diffractometer, its components, alignment, calibration, and automation. The first three chapters outline diffraction theory in clear language, accessible to both students and professionals in chemistry, physics, geology, and materials science. The book's middle chapters describe the instrumentation and procedures used in X-ray diffraction, including X-ray sources, X-ray detection, and production of monochromatic radiation. The chapter devoted to instrument design and calibration is followed by an examination of specimen preparation methods, data collection, and reduction. The final two chapters provide in-depth discussions of qualitative and quantitative analysis. While the material is presented in an orderly progression, beginning with basic concepts and moving on to more complex material, each chapter stands on its own and can be studied independently or used as a professional reference. More than 230 illustrations and tables demonstrate techniques and clarify complex material. Self-contained, timely, and user-friendly, Introduction to X-ray Powder Diffractometry is an enormously useful text and professional reference for analytical chemists, physicists, geologists and materials scientists, and upper-level undergraduate and graduate students in materials science and analytical chemistry. X-ray powder diffraction-a technique that has matured significantly in recent years-is used to identify solid samples and determine their composition by analyzing the so-called "fingerprints" they generate when X-rayed. This unique volume fulfills two major roles: it is the first textbook devoted solely to X-ray powder diffractometry, and the first up-to-date treatment of the subject in 20 years. This timely, authoritative volume features: * Clear, concise descriptions of both theory and practice-including fundamentals of diffraction theory and all aspects of the diffractometer * A treatment that reflects current trends toward automation, covering the newest instrumentation and automation techniques * Coverage of all the most common applications, with special emphasis on qualitative and quantitative analysis * An accessible presentation appropriate for both students and professionals * More than 230 tables and illustrations Introduction to X-ray Powder Diffractometry, a collaboration between two internationally known and respected experts in the field, provides invaluable guidance to anyone using X-ray powder diffractometers and diffractometry in materials science, ceramics, the pharmaceutical industry, and elsewhere.
