Chirogenesis in Chemical Science is an exciting new book that takes readers inside the world of chirality and chirogenesis, guided by Victor Borovkov and Riina Aav, both internationally renowned experts on chirality. Chirality is a fundamental property of the universe and has significance in different organic/inorganic materials, living organisms, and human beings. The basic principle of chirality is existence of an object in two mirror image forms, which are not superimposable. This phenomenon is widely seen in various fields of knowledge including mathematics, astronomy, physics, chemistry, biology and ranging in scale from galaxies to nuclear particles.In chemical science, chirality is generally associated with a single molecule or group of molecules, which symmetry properties belonging to the Cn or Dn point groups with the simplest example of sp3 carbon atom bonded to four different substituents. The dynamic processes of chirality generation, modulation, transfer, amplification, etc. are termed chirogenesis.This is a fast-growing and interdisciplinary field of research, which is widely seen in many natural systems (such as DNA double helix, the secondary alpha-helix structure of proteins, lipid membranes, saccharides, heme proteins, and other biological molecular objects) and various artificial systems. It is of prime importance not only for fundamental science but also for a number of practical applications in such areas as pharmacology and agrochemistry, perfumery and food industry, materials and polymer sciences, enantioselective catalysis and nonlinear optics, nanoscience and nanotechnology, molecular devices and chemical sensors, and others. Therefore, understanding the mechanisms and various influencing factors is of particular significance for smart control and further effective application of chirogenesis in chemistry.

Fundamentals of Supramolecular Chirality is a critical description of the start and advancement of supramolecular chirality. This book focuses on the noncovalent approach with some supplementary examples of covalent supramolecular chirality.This contribution to supramolecular chirality is not intended to be a mere catalogue and description of the work done. It also traces a philosophical path following the development and possible perspectives of this topic, providing not a review but a critical examination of the field.

The concept of nanoarchitechtonics was introduced to describe the correct manipulation of nanoscale materials in the creation of nano-devices and applications. Nanoarchitectonics has begun to spread into many fields including nanostructured materials synthesis, supramolecular assembly, nanoscale structural fabrications, materials hybridizations, materials and structures for energy and environmental sciences, device and physical application, and bio- and medical applications. Following on from the 2012 title Manipulation of Nanoscale Materials, Concepts and Design of Materials Nanoarchitectonics covers the introductory features underlying the field, presenting a unifying overview of the theoretical aspects and emerging applications that are changing the capability to understand and design advanced functional materials. Edited by pioneers of the field, this book will appeal to researchers working in nanoscience, materials science, supramolecular chemistry, physical chemistry and organic chemistry, as well as graduate students in these areas.

Supramolecular chemistry deals with the organisation of molecules into defined assemblies using non-covalent interactions, including weaker and reversible interactions such as hydrogen bonds, and metal-ligand interactions. The aspect of stereochemistry within such chemical architectures, and in particular chirality, is of special interest as it impacts on considerations of molecular recognition, the development of functional materials, the vexed question of homochirality, nanoscale effects of interactions at interfaces, biocatalysis and enzymatic catalysis, and applications in organic synthesis. Chirality in Supramolecular Assemblies addresses many of these aspects, presenting a broad overview of this important and rapidly developing interdisciplinary field. Topics covered include: Origins of molecular and topological chirality Homochirogenesis Chirality in crystallinity Host-guest behavior Chiral influences in functional materials Chirality in network solids and coordination solids Aspects of chirality at interfaces Chirality in organic assemblies Chirality related to biocatalysis and enzymes in organic synthesis. This book is a valuable reference for researchers in the molecular sciences, materials science and biological science working with chiral supramolecular systems. It provides summaries and special insights by acknowledged international experts in the various fields.

"How did life originate and why were left-handed molecules selected for its architecture?" This question of high public and interdisciplinary scientific interest is the central theme of this book. It is widely known that in processes triggering the origin of life on Earth, the equal occurrence, the parity between left-handed amino acids and their right-handed mirror images, was violated. The balance was inevitably tipped to the left – as a result of which life's proteins today exclusively implement the left form of amino acids. Written in an engaging style, this book describes how the basic building blocks of life, the amino acids, formed. After a comprehensible introduction to stereochemistry, the author addresses the inherent property of amino acids in living organisms, namely the preference for left-handedness. What was the cause for the violation of parity of amino acids in the emergence of life on Earth? All the fascinating models proposed by physicists, chemists and biologist are vividly presented including the scientific conflicts. The author describes the attempt to verify any of those models with the chirality module of the ROSETTA mission, a probe built and launched with the mission to land on a comet and analyse whether there are chiral organic compounds that could have been brought to the Earth by cometary impacts. A truly interdisciplinary astrobiology book, "Amino Acids and the Asymmetry of Life" will fascinate students, researchers and all readers with backgrounds in natural sciences. With a foreword by Henri B. Kagan.

With this collection of short review papers we would like to present a broad overview of research on poly?uorenes and related heteroanalogues over the last two decades. The collection begins with papers on the synthesis of po- ?uorenesandrelatedpolyheteroarenes, thenreportsphotophysicalproperties of this class of conjugated polymers both at the ensemble and the single chain level, continues with a discussion of the rich solid state structures of poly?uorenes, and ?nally switches to device applications (e.g. in OLEDs). In addition, two chapters are devoted to de?ned oligo?uorenesas lowmolecular weight model systems forpoly?uorenes and also to degradation studies. We feel that this up-to-date collection will be very helpful to all polymer chemists and physicists, and will also aid graduate students interested in this fascinating and still growing area of research, since such a compact overview is only now available. All articles are presented by leading scientists in their ?elds, insuring state-of-the-art coverage of all relevant aspects. Together with the body of references this volume is meant to assist researchers in the daily lab routine. Moreover, Advances in Polymer Science, as an established series of high quality review papers, represents a very appropriate platform for our project.Wehopethatthisshortcollectionwillbeofgreatvaluebothforbeg- ners and established researchscientists inthe?eldofpoly?uorene research.

This book entitled “Chemical Symmetry Breaking” is a collective volume of state-of-the-art reports on unique nonlinear chemical and physical symmetry-breaking phenomena that were experimentally observed upon a thermally or photochemically induced phase transition in various organic condensed phases, such as metastable liquid crystals, crystals, amorphous solids, and colloidal polymer materials, only under nonequilibrium conditions. Each author summarizes the introductory section in simple terms but in detail for beginners in this field. We wish that many readers familiarize themselves with the general concepts and features of nonlinear and nonequilibrium (or out of equilibrium) complexity theory, which govern a variety of unique dynamic behaviors observed in chemistry, physics, life science and other fields, so that they may discover novel symmetry-breaking phenomena in their own research areas.
