Organic Inorganic Hybrid Materials 2002

The MRS Symposium Proceeding series is an internationally recognised reference suitable for researchers and practitioners.

This book deals with one of the most attractive fields in material science and technology research. In fact, the concept of organic–inorganic hybrid materials is applied to a wide variety of approaches that include materials with inorganic and/or organic nature with respect to their matrices and/or dispersed phase. The present book compiles one editorial and eleven approaches to the topic, and intends to provide a transversal idea about what the field of the so-called organic–inorganic hybrid materials means in actual scientific scenarios. In any case, the role is pointed out of the interphase between the components as the critical aspect to consider, as a way to enhance and understand these components in order to design materials with "tailor-made" organized structures considering the increasing nano-, meso-, micro- and macro-scales.

The combination of supramolecular chemistry, inorganic solids, and nanotechnology has already led to significant advances in many areas such as sensing, controlled motion, and delivery. By making possible an unprecedented tunability of the properties of nanomaterials, these techniques open up whole new areas of application for future supramolecular concepts. The Supramolecular Chemistry of Organic–Inorganic Hybrid Materials gathers current knowledge on the subject and provides an overview of the present state and upcoming challenges in this rapidly growing, highly cross- or interdisciplinary research field. The book details how these designed materials can improve existing materials or generate novel functional features such as chemical amplification, cooperative binding and signal enhancement that are difficult or not at all achievable by classical organic supramolecular chemistry. It also discusses issues related to nanofabrication or nanotechnology such as the directed and controlled assembly or disassembly, biomimetic functions and strategies, and the gating and switching of surface functions or morphology.

This book provides extensive information on organic-inorganic hybrid materials with controllable compositions and structures developed over the past few decades, including metal sulfonates, carboxylates, phosphonates, metal-organic frameworks (MOFs), etc. A variety of judicious strategies for optimizing mesoporosity are also introduced, aiming at realizing the corresponding superiorities of hybrid frameworks in practical applications at the nano-/meso-scale. The morphological design and modification methods are also described in detail, which extend the potential application range of hybrid materials from traditional areas to high-tech fields. The book offers an ideal reference work for readers in the fields of chemistry, chemical engineering, physics, materials and biology, especially those who are interested in porous hybrid materials.

Interest in hybrid materials has accelerated recently, in particular because tailoring materials properties through organization of organic/inorganic composites at nanometer length scales is now an important focus for numerous diverse research domains. This book's objective here is to create a communal forum for researchers involved in all areas of organic/inorganic hybrid materials to share perspectives, to learn about leading-edge science and engineering occurring around the world, and to develop new ideas. The book is divided into focus areas that address synthesis and characterization methods, functional hybrid materials, hybrid materials influenced by biology, structured mesoporous materials and materials with multiscale organization. Topics include: methods of patterning hybrid materials; hybrid materials for photonic applications; mesoporous films and monoliths; biofunctional materials; layered hybrid materials; applications-oriented hybrid materials; hybrid materials for electronics, optoelectronics and semiconductor applications; methods of characterizing hybrid materials; and novel synthetic methods.
