Synthesis and host-guest interaction of cage-annulated podands, crown ethers, cryptands, cavitands and non-cage-annulated cryptands.
… our understanding of the role played by the host molecules in "cation-capture, anion-activation" via complexation with guest molecules. Thus, host-guest interaction serves not only to activate the anion but also may activate the leaving groups that participate in the complexation. …

Reactive Sieving With M-Phenylene Ethynylene Foldamers: Effects of Structural Modification on Reactivity
… attempt to further understand the nature of the host-guest interaction between mPE foldamers and the methylsulfonate esters used to study reactive sieving, a set of parameters for both the mPE foldamer and the methylsulfonate guests were developed for CHARMM-based molecular dynamics simulations. …

Quantification of Supramolecular Complexes Involving Charged Species in Non-Aqueous Solvents: Theory and Application
… by using either a ditopic cation and anion host, or adding to the charged host/guest solution a molecularly separate host capable of complexing the dissociated counterion. Also in accord with this model, we investigated the influence of the solvent¡¯s dielectric constant on Kipd and …

HIGH-PRESSURE BEHAVIOUR AND CRYSTAL-FLUID INTERACTION OF THE ABC-6 ZEOLITES: THE CASE OF ERIONITE, OFFRETITE AND BELLBERGITE
… by interconnection of channel and cage systems, hosting alkali/alkaline-earth cations and small molecules. The framework is composed of TO4 tetrahedral units. The International Zeolite Association (IZA) recognises the existence of more than 250 compounds with zeolitic structures, among those more …

Surface conjugation of upconversion nanoparticles via supramolecular host-guest self-assembly
… a system assemble themselves spontaneously via interaction to form a larger functional unit. In the view of thermodynamics, self-assembly is an equilibrium process where the assembled components are in equilibrium with the individual components. In other words, it is driven by the minimization …

Pinzettenförmige Moleküle mit Wasserstoffbrücken-Donor-Akzeptor-Einheiten : potentielle Kandidaten zur Anwendung in der dynamisch kombinatorischen Chemie
… These molecules are able to interact with guest species via hydrogen bonding. Building blocks for the libraries are tweezer-type molecules, which are obtained by coordinative metal-ligand-interactions or covalent aryl-ester-bonds. The formation of dynamic libraries should be possible by …

Host-Guest Assemblies for Functional Interfaces via Langmuir-Blodgett and Self-Assembly Technique
… events that are influenced by various molecular interactions at a solid-liquid interface. The functionality of a surface plays an important role in many applications such as catalysis, sensing, and bio-compatibility, which can benefit from distinctive chemical and physical surface properties. To …

To Couple or not to Couple? Exploring Vibronic Coupling in Organic Semiconductors
… separation rates, and non-radiative losses. The interaction between electronic excitations and vibrational degrees of freedom not only shapes energy conversion pathways but often dictates device efficiency limits. Controlling—or at the very least, understanding—this coupling is therefore …

Die Dissoziations- und Rekombinations-Reaktion von Jodmolekülen in mikroporösen Porosil-Kristalliten auf der Femtosekunden-Zeitskala
In dieser Arbeit wurde die unimolekulare Dissoziations- und Rekombinations-Reaktion von Jodmolekülen untersucht, die in mikroporösen Porosil-Kristalliten eingelagert waren. Hierfür wurden sowohl experimentelle Pump-Probe-Experimente als auch theoretische Untersuchungen auf der …
