In this thesis, Bernhard Schmidt describes his research into two fields in the chemical sciences: supramolecular and macromolecular chemistry. Schmidt first investigates cyclodextrins (CDs), which are well known for the formation of supramolecular host/guest complexes with hydrophobic molecules in aqueous solution. Schmidt then also examines reversible addition-fragmentation chain transfer (RAFT) polymerization as a well-suited toll for the synthesis of water-soluble end-functionalized polymers. The author skillfully combines both concepts as a powerful tool to access reversibly forming macromolecular architectures. The novel methods and architectures presented in this work are highly interesting from both a fundamental point of view as well as a basis for the design of efficient drug release systems. The work in this thesis has led to a number of publications in top peer-reviewed journals.

Connects fundamental knowledge of multivalent interactions with current practice and state-of-the-art applications Multivalency is a widespread phenomenon, with applications spanning supramolecular chemistry, materials chemistry, pharmaceutical chemistry and biochemistry. This advanced textbook provides students and junior scientists with an excellent introduction to the fundamentals of multivalent interactions, whilst expanding the knowledge of experienced researchers in the field. Multivalency: Concepts, Research & Applications is divided into three parts. Part one provides background knowledge on various aspects of multivalency and cooperativity and presents practical methods for their study. Fundamental aspects such as thermodynamics, kinetics and the principle of effective molarity are described, and characterisation methods, experimental methodologies and data treatment methods are also discussed. Parts two and three provide an overview of current systems in which multivalency plays an important role in chemistry and biology, with a focus on the design rules, underlying chemistry and the fundamental principles of multivalency. The systems covered range from chemical/materials-based ones such as dendrimers and sensors, to biological systems including cell recognition and protein binding. Examples and case studies from biochemistry/bioorganic chemistry as well as synthetic systems feature throughout the book. Introduces students and young scientists to the field of multivalent interactions and assists experienced researchers utilising the methodologies in their work Features examples and case studies from biochemistry/bioorganic chemistry, as well as synthetic systems throughout the book Edited by leading experts in the field with contributions from established scientists Multivalency: Concepts, Research & Applications is recommended for graduate students and junior scientists in supramolecular chemistry and related fields, looking for an introduction to multivalent interactions. It is also highly useful to experienced academics and scientists in industry working on research relating to multivalent and cooperative systems in supramolecular chemistry, organic chemistry, pharmaceutical chemistry, chemical biology, biochemistry, materials science and nanotechnology.

Document from the year 2012 in the subject Chemistry - Macromolecular Chemistry, Polymer Chemistry, Gurukula Kangri University, language: English, abstract: Supra-molecular chemistry is one of the most popular areas of experimental chemistry because of the presence of a number of supra-molecular assemblies in nature. SURFACTANTS and CROWN ETHERS, representing the Colloidal systems and Macrocycles respectively, are the two significant parts of supra-molecular chemistry. The present work is based on the aim to study the crown ether- surfactant interactions.

Composed of contributions from experts in the chemical and biological sciences, it explores host-guest molecular interactions leading to the formation of molecular assemblies containing two or more species. Exciting applications are emerging in this field and it is expected that improved understanding of the interactions in synthetic host molecule complexes will lead to a better understanding of the more complex biological systems. Topics include biomimetic chemistry, preorganization, self-assembly, template-directed synthesis, antibiotic binding to peptides and DNA, interactions between proteins and other molecules.

Container Molecules and Their Guests deals with the fundamental principles and objectives that govern this rapidly developing subject and illustrates the emergence of a new field of biomimetic chemistry. The book demonstrates how a number of techniques, such as molecular modelling, synthesis, crystal structure, NMR solution structure and mass spectral structure determinations can be combined to develop a new branch of organic chemistry. It discusses the chemistry of completely new families of complexes - the carceplexes, hemicarceplexes and velcraplexes - and reviews for the first time the uses of the interiors of hemicarceplexes as a new phase for carrying out chemical reactions and for protecting unstable species. Furthermore, it illustrates how complexation and decomplexation rates are measured to provide free energies of binding, discusses new phenomena such as constrictive binding, and shows how solvophobic forces drive complexation in a variety of organic solvents. It also covers catalysis through complexation and chiral recognition in catalysis, both secondary themes of this volume. Container Molecules and Their Guests will provide stimulating reading for researchers, post-graduate students and teachers involved in bio-organic chemistry, organic chemistry, materials science, and medicinal and pharmaceutical chemistry.
