Book Description
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.

Book Description
The series Advances in Polymer Science presents critical reviews of the present and future trends in polymer and biopolymer science. It covers all areas of research in polymer and biopolymer science including chemistry, physical chemistry, physics, material science. The thematic volumes are addressed to scientists, whether at universities or in industry, who wish to keep abreast of the important advances in the covered topics. Advances in Polymer Science enjoys a longstanding tradition and good reputation in its community. Each volume is dedicated to a current topic and each review critically surveys one aspect of that topic, to place it within the context of the volume. The volumes typically summarize the significant developments of the last 5 to 10 years and discuss them critically, presenting selected examples, explaining and illustrating the important principles and bringing together many important references of primary literature. On that basis, future research directions in the area can be discussed. Advances in Polymer Science volumes thus are important references for every polymer scientist, as well as for other scientists interested in polymer science - as an introduction to a neighboring field, or as a compilation of detailed information for the specialist. Review articles for the individual volumes are invited by the volume editors. Single contributions can be specially commissioned. Readership: Polymer scientists, or scientists in related fields interested in polymer and biopolymer science, at universities or in industry, graduate students.

Book Description
The development of materials with combined mechanical properties remains a significant challenge in polymer synthesis. The preparation of such materials could potentially impact a wide range of Army applications. In this work, bio-inspired metallo- supramolecular polymers were designed, synthesized, and characterized. We anticipate these polymers will display enhanced mechanical properties due to the presence of intermediate strength metal-ligand bonds present in the polymer backbone, which forms a compacted, modular molecular topology. The 2,6-bisbenzimidazolylpyridine ligand was prepared and incorporated into a model polymer backbone via thiol-ene click chemistry. The resulting polymer was thoroughly characterized by 1H Nuclear Magnetic Resonance (NMR), gel permeation chromatography (GPC), and differential scanning calorimetry (DSC). Binding of the ligand with Zn2+ and Co2+ was studied using ultraviolet/visible (UV/Vis) spectroscopy, which demonstrated a 2:1 ligand-to-metal ratio.

Book Description
There is great interest in metallosupramolecular materials because of their use in magnetic, photonic and electronic materials. Functional Metallosupramolecular Materials focuses on the applications of these materials covering the chemistry underlying the synthesis of a variety of ligands to coordinate various metal ions and the generation of 2D and 3D materials based on these constructs. The book starts by looking at different metallosupramolecular systems including naturally occurring functional metallosupramolecular materials; DNA-based metallosupramolecular materials; metallopolymers; metallogels as well as functional materials based on MOFs. Subsequent chapters then systematically cover the different applications such as molecular computation, spin-crossover, light harvesting and as photocatalysts for the production of solar fuels. The book provides an overview of functional metallosupramolecular materials that will be of interest to graduate students, academics and industrial chemists interested in supramolecular chemistry, materials science and the materials applications.

Book Description
Over the past decade, research on molecular gels has expanded and progressed rapidly. This timely book presents the latest developments and understanding of the topic, covering the different classes of gels (ionogels, metallogels, hydrogels and organogels) from their molecular level interactions and formation to their properties as materials and applications. The book starts with a general introduction to molecular gels including their definition and a comparison of the different types.
