Book Description
The Porphyrin Handbook, Volume 19: Applications of Phthalocyanines provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book examines the biology and medical implications of porphyrin systems. Organized into five chapters, this volume begins with an overview of the basic photobiology of phthalocyanines, their structure-activity relationships, mechanisms of action in a variety of biological systems, and their potential applications for various medical purposes. This text then examines the type of organization of the molecules in the solid state and the intensity of the intermolecular interactions. Other chapters consider the applications of phthalocyanines as decorative and functional materials, with emphasis on properties and structures of phthalocyanines with industrial relevance. This book discusses as well the enzyme-like catalytic functions of metal complexes derivatives and their practical applications as odor-removing systems and bacterial systems based on their effective catalytic activities. This book is a valuable resource for research scientists, engineers, and clinicians.

Book Description
The porphyrins are a class of naturally-occurring macrocycles and are ubiquitous in our world. As such, they have been called the Pigments of Life. This auspicious designation reflects their importance in numerous biological functions. Indeed, life as we understand it relies on the full range of biological processes that are either performed by or catalyzed by porphyrin-containing proteins. Chlorophyll-containing photosynthetic reaction centers in plants, for instance, convert light energy into chemical energy while producing oxygen along the way. It is this oxygen, evolved from photosynthesis, that is transported, stored, and reduced by heme-containing proteins in many organisms, including mammals. Not surprisingly, therefore, these molecules remain of fundamental interest to chemists and biochemists. Indeed, they continue to be intensely investigated by researchers world-wide.Inspired by the importance of the porphyrins, a new research direction has emerged in recent years that is devoted to the preparation and study of non-porphyrin polypyrrole macrocycles. Here, the principal objectives have been to generate completely synthetic systems that bear some structural resemblance to naturally-occurring porphyrin derivatives while being quite different in their specific chemical makeup. Within this context, three different research directions have evolved, namely those involving the syntheses of contracted, isomeric, and expanded porphyrins, respectively. It is the chemistry of these systems that is the subject of this book. Because of the newness of the field, the emphasis of this book will be on synthesis and characterization (all work on porphyrin isomers and much of that associated with expanded porphyrins has only appeared in the last 10 years). One chapter on applications has, however, been included. Also, in the context of the preparative portions of the text, some efforts have been made to explain why various porphyrin analogue targets are of interest.

Book Description
"Life Is Bottled Sunshine" [Wynwood Reade, Martyrdom of Man, 1924]. This inspired phrase is a four-word summary of the significance of photosynthesis for life on earth. The study of photosynthesis has attracted the attention of a legion of biologists, biochemists, chemists and physicists for over 200 years. Discoveries in Photosynthesis presents a sweeping overview of the history of photosynthesis investigations, and detailed accounts of research progress in all aspects of the most complex bioenergetic process in living organisms. Conceived of as a way of summarizing the history of research advances in photosynthesis as of millennium 2000, the book evolved into a majestic and encyclopedic saga involving all of the basic sciences. The book contains 111 papers, authored by 132 scientists from 19 countries. It includes overviews; timelines; tributes; minireviews on excitation energy transfer, reaction centers, oxygen evolution, light-harvesting and pigment-protein complexes, electron transport and ATP synthesis, techniques and applications, biogenesis and membrane architecture, reductive and assimilatory processes, transport, regulation and adaptation, Genetics, and Evolution; laboratories and national perspectives; and retrospectives that end in a list of photosynthesis symposia, books and conferences. Informal and formal photographs of scientists make it a wonderful book to have. This book is meant not only for the researchers and graduate students, but also for advanced undergraduates in Plant Biology, Microbiology, Cell Biology, Biochemistry, Biophysics and History of Science.

Book Description
This is the first set of Handbook of Porphyrin Science.Porphyrins, phthalocyanines and their numerous analogues and derivatives are materials of tremendous importance in chemistry, materials science, physics, biology and medicine. They are the red color in blood (heme) and the green in leaves (chlorophyll); they are also excellent ligands that can coordinate with almost every metal in the Periodic Table. Grounded in natural systems, porphyrins are incredibly versatile and can be modified in many ways; each new modification yields derivatives demonstrated new chemistry, physics and biology, with a vast array of medicinal and technical applications.As porphyrins are currently employed as platforms for study of theoretical principles and applications in a wide variety of fields, the Handbook of Porphyrin Science represents a timely ongoing series dealing in detail with the synthesis, chemistry, physicochemical and medical properties and applications of polypyrrole macrocycles. Professors Karl Kadish, Kevin Smith and Roger Guilard are internationally recognized experts in the research field of porphyrins, each having his own separate area of expertise in the field. Between them, they have published over 1500 peer-reviewed papers and edited more than three dozen books on diverse topics of porphyrins and phthalocyanines. In assembling the new volumes of this unique Handbook, they have selected and attracted the very best scientists in each sub-discipline as contributing authors of the chaptersThis Handbook will prove to be a modern authoritative treatise on the subject as it is a collection of up-to-date works by world-renowned experts in the field. Complete with hundreds of figures, tables and structural formulas, and thousands of literature citations, all researchers and graduate students in this field will find the Handbook of Porphyrin Science an essential, major reference source for many years to come.

Book Description
Macrocyclic molecules contain rings made up of seven or more atoms. They are interesting because they provide building blocks for synthesizing precise two or three dimensional structures – an important goal in nanotechnology. For example, they can be used to develop nanosized reaction vessels, cages, switches and shuttles, and have potential as components in molecular computers. They also have applications as catalysts and sensors. Macrocycles: Construction, Chemistry and Nanotechnology Applications is an essential introduction this important class of molecules and describes how to synthesise them, their chemistry, how they can be used as nanotechnology building blocks, and their applications. A wide range of structures synthesised over the past few decades are covered, from the simpler cyclophanes and multi-ring aromatic structures to vases, bowls, cages and more complex multi-ring systems and 3D architectures such as “pumpkins”, interlocking chains and knots. Topics covered include: principles of macrocycle synthesis simple ring compounds multi-ring aromatic structures porphyrins and phthalocanines cyclophanes crown ethers, cryptands and spherands calixarenes, resorcinarenes, cavitands, carcerands, and heterocalixarenes cyclodextrins cucurbiturils cyclotriveratylenes rotaxanes catenanes complex 3D architectures, including trefoils and knots Macrocycles: Construction, Chemistry and Nanotechnology Applications distills the essence of this important topic for undergraduate and postgraduate students, and for researchers in other fields interested in getting a general insight into this increasingly important class of molecules.
