Aims and Scope

The seriesStructure 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 fallwithin the purview ofStructure 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. In referencesStructure and Bonding is abbreviated Struct Bond and is cited as a journal.

Preface

Photofunctional materials are a large family of photoactive compounds that can transfer, absorb, store, switch, or utilize light energy. Layered compounds with two-dimensional (2D) structures have recently emerged as a new platform for developing novel photofunctional materials and have already been explored and applied in the fields of light-harvesting, photoluminescence, photocatalysis, bio-logical imaging, band structure engineering, photochromic sensors, and optoelec-tronic devices.

Given the rapid development of photofunctional layered materials, we believe the collection of reviews in this volume is timely. In the first chapter, Yan and colleagues review the photofunctionality of layered double hydroxide (LDH) materials, with a particular focus on the incorporation of organic chromophores, polymers, metal complexes, and quantum dots in LDHs; the fluorescence, optical sensing, and IR/UV absorption properties of the resulting composite materials are covered.

Although similar to LDH materials, layered rare earth hydroxides (LREHs)— which contain rare earth hydroxide cationic host layers—have been recognized as a new class of multifunctional materials with an intercalation ability that leads to extensive host–guest chemistry. In the second chapter, Sasaki and colleagues provide an overview of the development of LREH materials and summarize the synthetic methods, structure characterization, as well as their photoluminescence properties.

Photocatalytic materials have attracted great attention in environmental science, as well as in energy storage and transfer. In the third chapter, Wei et al. summarize the synthesis and photocatalytic applications of LDH-based materials. In particular, several important photocatalytic systems—such as pollutant degradation, water splitting for solar fuel production, and reduction of CO2 to useful carbon mate-rials—are reviewed and discussed.

widely developed. In the fourth chapter, Choy et al. review the structural chemistry of bio-LDH nanohybrid systems and summarize their applications in gene and drug delivery (in both therapeutics and diagnostics).

Photoresponsive materials (such as photochromic compounds) are regarded as one of the most interesting photo-related topics. In the fifth chapter, Ogawa et al. provide an overview of the development of photochromic intercalation compounds and describe how the formation of different layered host materials allows control over the orientation and aggregation of photochromic guests as well as the resulting photoresponsive properties.

As 2D functional units, graphene and its derivatives have attracted considerable interest due to their novel optical, electronic, mechanical, and surface properties. Recently, photogenerated free radicals have been shown to provide a new way for the covalent functionalization and band structure engineering of graphene. In the final chapter of this volume, Zhang and Liu discuss the photochemistry of graphene, including its photohalogenation, photoarylation, photoalkylation, and photocatalytic oxidation.

There has been an explosive growth in publications dealing with photofunctional layered materials in recent years. The reviews in this volume have attempted to cover representative examples of such layered compounds in the literature published up to 2014. Many interesting additional examples involving layered structures and novel photofunctionalities may have been excluded, either inadver-tently or due to space limitations, but we hope that the volume has captured the more important developments.

We express our thanks to all the authors for helping us capture the essence of recent research in this field.
