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.

Paperback. 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 di

This book provides an up-to-date survey of modern industrial inorganic chemistry in a clear and concise manner. Production processes are described in close detail, aspects such as the disposition of raw materials and energy consumption, the economic significance of the product and technical applications, as well as ecological problems, being discussed. From reviews of the previous edition: '... Overall this is an extremely useful, authoritative reference book dealing with a topic in which it is often difficult to obtain up-to-date information. ...' Chemistry and Industry 'One of few texts available that concisely describes the current state of industrial inorganic chemistry. ...' The New York Public Library '... and as for modern uses of inorganic chemistry, I'd recommend this book as a welcome addition to any professional library...' Chemtech 'This book fills an important niche in its sector. Industrial scientists and engineers, academics, and students can be recommended to turn to it with reasonable confidence that the most important areas are described. ...'

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.

This expanded fourth edition defines and cross-references 9,040 homophones and 2,133 homographs (up from 7,870 and 1,554 in the 3rd ed.). As the most comprehensive compilation of American homophones (words that sound alike) and homographs (look-alikes), this latest edition serves well where even the most modern spell-checkers and word processors fail--although rain, reign, and rein may be spelled correctly, the context in which these words may appropriately be used is not obvious to a computer.

On August 18, 1977 a special 'Soddy Session' was held at the Fifteenth International Congress of the History of Science, Edinburgh, Scotland, with Dr. Thaddeus J. Trenn as Symposium Chairman. This session was organized to commemorate the lOOth anniversary of the birth of Fre derick Soddy (born September 2, 1877, Eastbourne, England; died September 22, 1956, Brighton, England), who was awarded the 1921 Nobel Prize in Chemistry 'for his contributions to our knowledge of the chemistry of radioactive substances, and his investigations into the origin and nature of isotopes'. Soddy taught and/or carried out research at Oxford University (where he was Lee's Professor of Chemistry), McGill University (where he and Sir Ernest Rutherford proposed the disintegration theory of radioactivity), University College, London (where he and Sir William Ramsay demonstrated natural transmuta tion), Glasgow University (where he formulated his displacement law and concept of isotopes), llnd Aberdeen University. In addition to his contributions to radiochemistry, he proposed a number of controversial economic, social, and political theories. The present volume contains the eight lectures presented at the symposium, two additional papers written especially for this volume (Kauffman, Chapter 4 and Krivomazov, Chapter 6), a paper on Soddy's economic thought (Daly, Chapter 11), and three selections from Soddy's works. Furthermore, an introductory account of Soddy's life and work by Thaddeus J. Trenn as well as a Soddy chronology, and name and subject indexes compiled by the editor are provided.
