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.

Barone and published by . This book was released on 2008 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The metal binding chemistry of porphyrin analogs is a rapidly growing area of research. One specific family of analog where one or more of the internal nitrogen positions has been replaced by carbon, known as the carbaporphyrins, is of interest to researchers due to novel organometallic interactions with various metals in the interior of the ring. Within this thesis, a continued investigation of the carbahemiporphyrazines, anti-aromatic phthalocyanine analogs where one or more isoindolene rings has been replaced with benzene rings is presented. The theory, synthesis and characterization of oxygen containing hemiporphyrazines analogues are investigated. These types of oxygen containing rings incorporate either phenol or resorcinol into a carbahemiporphyrazine ring. Due to the redox activity of the phenol or resorcinol, these macrocycles can potentially become aromatic upon oxidation in a fashion similar to that seen in the oxybenziporphyrins. As in the carbahemiporphyrazines, these rings can bind metal ions, forming novel organometallic interactions at the core of the ring. Also presented within this thesis is the single crystal X-ray diffraction characterization of new rhenium(I) tri-carbonyl complexes for possible application as radiopharmaceutical diagnostics. The Re(I) compounds designed to be analogs for next generation d6 technetium imaging agents. These compounds are synthesized in aqueous conditions and are stable upon exposure to air. The single crystal X-ray diffraction elucidation of the Re(I) compounds are grouped into three distinct categories: monodentate complexes, bidentate complexes and tridentate complexes. All of the complexes are octahedral, and the carbonyl ligands arranged in a facial configuration. The complexes are synthesized from the Re(CO)3(H2O)+ synthon.

Book excerpt: The Porphyrin Handbook, Volume 17: Phthalocyanines: Properties and Materials 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 effects of pressure, temperature, electromagnetic radiation, and particle impact on phthalocyanines. This text then examines. Other chapters consider the research on phthalocyanine thin films, with emphasis on studies that are concerned primarily with film structures. This book discusses as well the nature of the phthalocyanine aggregation process, how an aggregate is defined, and the issues of its bonding and structure. The final chapter deals with the advances in the design of composites of phthalocyanines or porphyrins and inorganic hosts and some of the most significant finding in the catalysis with these systems. This book is a valuable resource for research scientists, engineers, and clinicians.

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.

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
