Book Description
A comprehensive overview about the emerging field of photoswitches and their applications in materials science and biology Molecular Photoswitches guides the reader through the basic molecular structures of photochromic compounds and their applications in the area of photoresponsive materials as well as in the biological context. The initial chapters describe individual classes of molecular photoswitches, introducing their principles of photochromism, typical switching wavelengths, thermal stability of photoisomers and other key information, which is ordinarily spread in the literature. These classes comprise i.a. azobenzenes, diazocines, arylazoheterocycles, arylhydrazones, indigoids, photochromic imines, or acylhydrazones. The book also covers: Catalysis with molecular switches Applications in photochromic porous materials, liquid crystals, or nanoparticles Light-responsive molecular machines, logic devices, and molecular magnets Photomodulation of biological systems: photoswitchable biopolymers, lightmodulated antibiotics, cytotoxins, ion channel inhibitors, light-propelled artificial muscles, and computationally designed photochromic proteins This two-volume work is a valuable guide for researchers and non-experts working in the field of photochemistry, organic chemistry, catalysis, materials science, biology, and medicine.

Book Description
In the course of the last twenty years, the research interest in 'photochemical switches' highly increased. They react on light, which can be controlled with excellent spatiotemporal precision, yet it is orthogonal towards most elements of chemical and biochemical systems. Therefore, light is an attractive trigger to control or study biological function or functional materials. In this work, the excellent properties of azobenzene photoswitches were combined with the cyclic dipeptide structural motif, resulting in phototriggered supramolecular low-molecular-weight gelators (LMWGs). Hydrogels are soft materials, which often find application in biomedical context and can be formed by self-assembly of LMWGs. They classify by their self-healing properties, thixotropy, on-demand reversibility and stimuli responsiveness, for example to light. The photoswitches inside photochromic hydrogels react in spatiotemporal precision to light irradiation and are excellent candidates for photo-controlled drug release. The versatility of azobenzene containing DKP-Lys hydrogelators was demonstrated in this thesis.

Book Description
This volume combines reviews on the latest advances in photochemical research with specific topical highlights in the field. Starting with periodical reports of the recent literature on organic and computational aspects including reports on computational photochemistry and chemiluminescence of biological and nanotechnological molecules, photochemistry of alkenes, dienes and polyenes, aromatic compounds and oxygen-containing functions. The final chapter of this section is a review of industrial application of photochemistry from 2014 to 2019. Coverage continues with highlighted topics, in the second part, from ruthenium-caged bioactive compounds, advances in logically and light induced systems, developments of metal-free photocatalysts, photoresponsive organophosphorus materials and applications of photo-fragmentation in synthesis, photo-click chemistry and azo-based molecular photoswitches. This volume will again include a section entitled ‘SPR Lectures on Photochemistry’, a collection of examples for academic readers to introduce a photochemistry topic and precious help for students in photochemistry. Providing critical analysis of the topics, this book is essential reading for anyone wanting to keep up to date with the literature on photochemistry and its applications. "A certain amount of energy destroys the same amount of CO2 according to the whether it is administered continuously or intermittently. In order to rationalize this result there are two possibilities, either the destruction of CO2 further occurred in the dark periods, which would lead to the same form of energy storing form, or in the illuminated period the reaction goes at twice the rate."

Book Description
The historical achievements in organic natural product synthesis can be recognized most clearly in the research accomplishments of Albert Eschenmoser. For example, his work on the chemical synthesis of vitamin B12 defined the frontier in organic natural product synthesis and profoundly influenced the science of organic chemistry. In addition to revealing the beautiful reaction pathways leading to compounds of great biochemical significance, Albert Eschenmoser has contributed innovative methods of outstanding utility for organic synthesis. Few individuals have so fundamentally influenced the science of organic chemistry as Albert Eschenmoser has. Over the years, a sizable fraction of Albert Eschenmoser′s work has been published in Helvetica Chimica Acta, hence the decision of the Editor to produce a special issue of the journal on the occasion of Albert Eschenmoser′s 75th birthday, celebrated on August 5, 2000. The highly impressive set of 67 original research papers submitted in response to the Editor′s invitation could not, for obvious technical reasons, be accommodated in a single issue and were thus divided over the August and September issues. The international reaction to this tribute has been so overwhelmingly enthusiastic that the two issues have been combined in this single volume for separate publication.
