Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: FUNDAMENTALS OF PORPHYRIN CHEMISTRY An indispensable and concise overview of the chemistry of porphyrins and related molecules In Fundamentals of Porphyrin Chemistry: A 21st Century Approach, a team of distinguished researchers delivers a compact and accessible introduction to the broad field of porphyrin chemistry. It discusses the basics of porphyrin synthesis and structure, as well as that of related molecules, and the current and future roles that porphyrins play in chemical transformations, materials design and synthesis, energy capture and transduction, human health, and the environment. This edited volume is a self-contained tutorial on concepts of critical importance to porphyrin chemistry and serves as the foundation for discussions about the applications of porphyrin-related compounds found in the second volume. This book contains: A thorough introduction to porphyrins, including their structure, nomenclature, naturally occurring porphyrins, synthetic porphyrins, and common families of porphyrin-related compounds Comprehensive explorations of chemical porphyrin synthesis, including how to synthesize porphyrins from simple, symmetric, and advanced ABCD-substituted porphyrins Practical discussions of the physical characteristics of porphyrins, including their structural features, electronic structure, spectroscopy, magnetism, electrochemistry, and electron transfer processes Perfect for experienced academic researchers in the field of porphyrin chemistry seeking a quick reference, Fundamentals of Porphyrin Chemistry: A 21st Century Approach is also an indispensable resource for researchers new to the field who need an overview directing them to literature in more focused areas.

Download or read book Synthesis & Characterization of New Amethyrin-based Expanded Porphyrin Metal Complexes written by James Thomas Brewster (II) and published by . This book was released on 2017 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: New expanded porphyrins are of interest in terms of understanding the electrochemical features of oligopyrroles and the determinants of aromaticity. They can also act as ligands to stabilize metal complexes whose structures can differ from those of the better-studied porphyrins and, separately, have been explored for use in photodynamic and radiation therapy, among other application areas. With these considerations in mind, Chapter 1 is designed to provide a brief introduction to expanded porphyrin chemistry. Chapter 2 serves to detail our work on an expanded porphyrin called dipyriamethyrin. The emphasis will be on its preparation and the synthesis of the uranyl complex. Chapter 3 furthers this discussion with the synthesis of a related system, naphtho-isoamethyrin, as well as its bis-copper and uranyl complex. All work not carried out by the author will be specified as to give credit to those who provided the much appreciated help and guidance. Furthermore, the author hopes to present the science in such a manner wherein both the novice and expert can appreciate and understand the beauty of the underlying science

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Porphyrins and their analogs are a class of chemically and biologically important compounds that have found a variety of applications in different fields such as catalysis, medicine, and materials. The physical, chemical, and biological dependence of the peripheral substituents of porphyrins on their properties has prompted great effort towards the synthesis of new porphyrins with different electronic, steric, and conformational environments. To this end, porphyrins have been prepared using a modular approach from bromo- and triflate synthons. These synthons underwent palladium-catalyzed cross-coupling with chiral amines, amides, alcohols, and boronic esters to create products that were tested for biological activity. Metalloporphyrins were screened as catalysts for cyclopropanation and C-H amination, yielding excellent results. By changing the porphyrin catalystsa[rsquo] chiral groups, all four enantiomers could be produced in the cyclopropanation of styrene derivatives with ethyl diazoacetate (or t-butyl diazoacetate). Similarly, a variety of sultams were produced from benzenesulfonyl azides in high yields and high enantioselectivities using chiral cobalt porphyrins as catalysts. Porphyrins, metalloporphyrins, and the catalytic products generated were tested for activity in a variety of medicinal collaborations, namely as therapeutics for methicillin-resistant Staphylococcus aureus, Alzheimera[rsquo]s disease, malaria, viral infections that include influenza and herpes, and cancer, as well as biological studies with ferrochelatase. They were also used in materials experiments with two different polymer groups.

This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the first and long-sought successful synthesis of a new pyrazole-expanded porphyrin, a higher analog of porphyrin. This "Siamese-Twin Porphyrin" provides two conjoined porphyrin-like coordination spheres, thus being able to accommodate two metal ions within the same ligand. In her thesis, Lina Blusch not only explains the challenging synthesis and characterization of the ligand system, but also its application to the synthesis of homo- and hetero-bimetallic Ni and Cu complexes. She observes interesting metal-metal-interactions in the complexes, that lead to a non-innocent multistep redox chemistry. The ligand system and its complexes show an intriguing twisted geometry, giving rise to helical chirality and other fascinating properties. This study explores the first steps and opens up a new chemistry of expanded porphyrins with the potential to biomimetic applications.
