In this book the authors describe how they reproduced the redox functions of biocatalysts artificially. It includes the introduction and discussion of synthetic reactions via electron transfer, hybrid -conjugated systems, and biorganometallic conjugates as novel redox systems. The work was conducted in pioneering fields based on redox systems, in synthetic organic chemistry, synthetic materials chemistry, and bioorganometallic chemistry. The step-by-step process is illustrated by the three major parts of the book: redox reactions (selective synthetic methods using metal-induced redox reactions), redox systems (design and redox function of conjugated complexes with polyanilines or quinonediimines and molecular bowl sumanene), and design of bioorganometallic conjugates to induce chirality-organized structures (bio-related structurally controlled systems). This systematic and up-to-date description will be of special interest to graduate students who are meeting the new challenges of chemistry, as well as to post-doctoral researchers and other practicing chemists in both academic and industrial settings.

3.1.1 ?-Conjugated Materials ?-conjugated polymers (CPs) and oligomers are materials with an extended ?-system along the backbone. The materials possess many remarkable prop- ties, including high charge carrier mobilities, electrical conductivities (doped), electrochromism, and electroluminescence [1]. These properties have been taken advantage of in exploration of potential applications including in ch- ical sensors, light-emitting devices, and ?eld-effect transistors. Many efforts have been devoted to synthesizing new conjugated polymers and oligomers in an effort to increase their processibility, optimize the desirable properties, and explore new properties. In Fig. 3.1 are shown examples of some of the CPs that have been prepared and studied. Coupling ?-conjugated materials to metal complexes gives hybrid mate- als in which the properties of the metal complex may be coupled to those of the conjugated backbone [2]. For example, these materials could be used in energy-harvesting devices such as solar cells or polymer-based light-emitting devices,wherehighchargecarrier mobilities of theconjugatedmaterialmay be combined with either the light-absorbing or emitting metal groups, giving improved device performance [3, 4]. In addition to an electronic role, metal complexes may also be used to geometrically orient ?-conjugated materials in speci?c three-dimensional arrangments in the solid state. Careful conside- tion of theelectronicinteractionsand excitedstatesisnecessary for thedesign of functional materials of this type.

Advances in Bioorganometallic Chemistry examines the synthesis, structure and reactivity of bioorganometallics, their pharmaceutical applications, hydrogenase, vitamin B12-like systems, and metalloproteins. It is written by the top researchers in the field and compiled by editors Toshikazu Hirao and Toshiyuki Moriuchi. Developments in this new field of bioorganometallic chemistry, a hybrid between biology and organometallic chemistry, happen very quickly and this comprehensive reference offers the latest research and findings in the field. The book features a discussion of the synthesis, structure, and reactivity of bioorganometallics, and an examination of hydrogenase-like systems, which were designed to demonstrate catalytic activities and functional properties. Advances in Bioorganometallic Chemistry also includes a discussion of bioorganometallics as they relate to medicinal chemistry, specifically applications of metalloproteins, metalloenzymes, and applications in bioimaging. The book concludes with coverage of vitamin B12-like systems, including the latest developments in derivatives designed to perform bio-inspired catalytic reactions. This work is a valuable resource for chemists working in organometallic chemistry and biology, including biochemists, bioorganic chemists, bioinorganic chemists, as well as pharmaceutical scientists, medicinal chemists, and students studying in these areas.
