Download or read book Electronic Communication in Heterometallated Porphyrin Oligomers written by Jonathan Cremers and published by Springer Nature. This book was released on 2020-02-13 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book cuts across the divisions of organic, inorganic, and physical chemistry. It describes new methods for creating π-conjugated porphyrin oligomers with precisely defined sequences of zinc and copper metal cations, and how EPR spectroscopy was used to investigate the dipolar and exchange coupling between the paramagnetic copper(II) centres. Porphyrins are a group of heterocyclic macrocycle organic compounds that play an important role in our everyday life and can for example be found in blood where they form a red complex with iron (haem). Various metallic elements can be inserted into a porphyrin and changing the coordinated metal is an excellent way to influence the chemical and physical properties of these molecules. Focusing on 3 metals - zinc, magnesium and copper - the author established new methods for creating π-conjugated porphyrin oligomers and lastly presents the synthesis and investigation of two novel porphyrin nanoballs. Giving the template-directed strategy the author developed for constructing these molecules, this work could provide access to other related nano-cages.

Download or read book Gold Clusters Colloids and Nanoparticles I written by D. Michael P. Mingos and published by Springer. This book was released on 2014-09-27 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors. Readership: research scientists at universities or in industry, graduate students Special offer For all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink.

Download or read book Expanded Contracted Isomeric Porphyrins written by Jonathan L. Sessler and published by Elsevier. This book was released on 1997 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: This book presents mechanics miniaturization trends explored step by step, starting with the example of the miniaturization of a mechanical calculator. The ultra-miniaturization of mechanical machinery is now approaching the atomic scale. In this book, molecule-gears, trains of molecule-gears, and molecule motors are studied -one molecule at a time- on a solid surface, using scanning probe manipulation protocols and in solution as demonstrated in the European project "MEMO". All scales of mechanical machinery are presented using the various lithography techniques currently available, from the submillimeter to the nanoscale. Researchers and nanomechanical engineers will find new inspirations for the construction of minute mechanical devices which can be used in diverse hostile environments, for example under radiation constraints, on the surface membrane of a living cell or immersed in liquid. The book is presented in a format accessible for university students, in particular for those at the Master and PhD levels.
