Available in PDF, EPUB and Kindle. Book excerpt: Organic Mechanochemistry and Its Practical Applications gathers physical and organic chemistry-based molecular principles, evolving interpretations of scientific data, and real world applications to demonstrate the synthetic advantages of mechanically initiated organic reactions. This book considers transformations of organic substances upon mechanical actions and explains how mechanical energy is transformed into chemical driving force. The author, a renowned expert in physical and organic chemistry, carefully examines the concurrent chemical and physical processes—particularly polymerization and dynamic shearing—that involve organic substances and inorganic surfaces during lubrication. Dr. Todres discusses the various factors that affect boundary lubrication, such as material properties, chemical reactivity, pressure, and temperature. The book describes conformational transformations and structural phase transitions of organic molecules and working materials that take place under mechanical forces, such as drilling, grinding, friction, and shearing, and shock-waves. Other key topics include mechanochromism, tribopolymerization, mechanical activation of organic reactions, and the peculiarities of catalytic effects in organic mechanochemistry. Throughout the text, the author highlights novel technical applications of mechanochemical phenomena in a variety of fields, including lubrication, biomedical engineering, pharmaceutical drug formulation, environmental protection, and practical economy. Organic Mechanochemistry and Its Practical Applications reveals how mechanochemistry was inspired by principles in various disciplines to create innovative approaches for current challenges in these fields.

Download or read book Mechanochromism written by David J. Fisher and published by Materials Research Forum LLC. This book was released on 2019-07-20 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanochromism (or piezochromism) refers to the emission of radiation as a result of the stressing, deforming or breaking of solids. The great current interest in these processes is due to the immense potential for monitoring and recording stresses, wear and fracture. There is, for instance, the possibility of turning such materials into optical pressuresensors and structural damage sensors. Mechanochromic polymers, for example, could visually signal sub-micron damage and failure long before macroscopic cracks became detectable. The range of such high-tech applications is almost unlimited. The book references 325 original resources and includes their direct web link for in-depth reading.

Download or read book Novel Luminescent Crystalline Materials of Gold I Complexes with Stimuli Responsive Properties written by Mingoo Jin and published by Springer Nature. This book was released on 2020-04-18 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights and investigates novel solid-state luminescent properties of crystals with stimuli-responsive behavior. Several novel molecular designs for controlling crystal structures with photo-physical properties are described, with a special focus on external stimuli-responsive properties. The major goal of the material design concept was to capitalize on the chirality of crystals with stimuli-responsive properties. To allow crystals’ chirality to be controlled and modified by means of external stimulation, the axial chirality of biaryl moiety was employed and, interestingly, produced several novel mechano- and vapo-responsive luminescent properties based on crystal-to-crystal or single-crystal-to-single-crystal phase transitions. In addition, the book details how the molecular rotation of luminophores in the solid phase can be used to achieve corresponding thermal-responsive phosphorescence. The reports presented here illustrate how the author has succeeded in controlling structural factors in a bulk environment by using molecular design with linking to photo-physical properties. The content will be of great interest to researchers in the field, and to members of chemical and material science societies.

Download or read book Aggregation of Luminophores in Supramolecular Systems written by Neetu Tripathi and published by CRC Press. This book was released on 2020-05-06 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supramolecular aggregation—driven by weak non-covalent interactions, such as van der Waals, π–π interactions, hydrogen bonding, and electrostatic—has been utilized to build sensing platforms with improved selectivity and sensitivity. Supramolecular aggregates, owing to cooperative interactions, higher sensitivity and selectivity, relatively weak and dynamic non-covalent interactions, and environmental adaptation, have achieved better sensing performance than that of molecular sensory systems that rely on sensors with delicate structures. Aggregation of Luminophores in Supramolecular System: From Mechanisms to Applications describes recent advances in supramolecular chemistry, in which the luminophores are almost non-luminescent in the molecular state, but become highly emissive in the aggregate state. These advances bring new opportunities and challenges for the development of supramolecular chemistry. The intermolecular non-covalent interactions have been considered to be the main driving forces for fabricating supramolecular systems with aggregating luminophores and have an important influence on the luminescence properties of the probes. Based on these unique properties, luminescent supramolecular aggregates have greatly promoted the development of novel materials for applications as sensors, bio-imaging agents, organic electronic devices, and in the field of drug delivery. Features: Discussion of fundamental and interdisciplinary aspects of the aggregation in supramolecular systems. Narration of intermolecular interactions and the photophysical phenomenon of aggregation in supramolecular systems. Comparative discussion on recent developments in aggregation-induced quenching (AIQ) and aggregation-induced emission (AIE), and drawbacks of AIQ. Description of the technological applications of aggregation as biological sensors, chemical sensors, organic electronic materials, and in the field of drug delivery. A convenient format for checking formulas and definitions. This book surveys highlights of the progress made in the field of the aggregation of luminophores in supramolecular chemistry. It is hoped that the work will form a foundation (and indeed a motivation) for new workers in the area, as well as also being useful to experienced supramolecular chemists. It may also aid workers in the biological area to see Nature’s aggregation in a new light. Further, the approach employed has been designed to provide readable background material for use with graduates, senior undergraduates, research professionals, and industries.

Download or read book Polymorphism in Molecular Crystals written by Joel Bernstein and published by Oxford University Press. This book was released on 2020-04-28 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most people are familiar with the fact that diamond and graphite are both composed only of carbon; yet they have very different properties which result from the very different structures of the two solids - they are polymorphs of carbon. Understanding the relationship between the structures and the properties of materials is of fundamental importance in developing and producing new materials with improved or new properties. The existence of polymorphic systems allows the direct study of the connection between structures and properties. This book provides grounding on the fundamental structural and energetic basis for polymorphism, the preparation and characterization of polymorphic substances and its importance in the specific areas of pharmaceuticals, pigments and high energy (explosive) materials. The closing chapter describes the intellectual property implications and some of the precedent patent litigations in which polymorphism has played a central role. The book contains over 2500 references to provide a ready entry into the relevant literature.
