We used dynamic (1)H NMR spectroscopic methods to examine the kinetics and thermodynamics of CH(3)CCl(3) (2) entering and leaving the gated molecular basket 1. We found that the encapsulation is first-order in basket 1 and guest 2, while the decomplexation is zeroth-order in the guest. Importantly, the interchange mechanism in which a molecule of CH(3)CCl(3) directly displaces the entrapped CH(...

Synthetic host-guest chemistry is a versatile tool for biomedical applications. Characterization and detection of host-guest complexes in biological systems, however, is challenging due to the complexity of the biological milieu. Here, we describe and apply a mass spectrometric method to monitor the association and dissociation of nanoparticle (NP)-based host-guest interactions that integrates ...

Host–guest chemistry encompasses the study of highly structured molecular complexes composed of at least two entities associated by noncovalent interactions, one possessing convergent binding sites, the host, and another possessing divergent binding sites, the guest. Among other species, the host can be a crown ether, calixarene, or metallacycle, whereas the guest can be virtually any small-tom...

In this work we investigate the security of security-critical applications, i.e. applications in which a failure may produce consequences that are unacceptable. We consider three areas: mobile devices, virtualization platforms, and domain name systems. The Java Micro Edition platform defines the Mobile Information Device Profile (MIDP) to facilitate the development of applications for mobile de...

We report a new and highly versatile approach to artificial layered materials synthesis which borrows concepts of molecular beam epitaxy, self-assembly, and graphite intercalation compounds. It readily yields stacks of graphene (or other two-dimensional sheets) separated by virtually any kind of "guest" species. The new material can be "sandwich like", for which the guest species are relatively...

Calixarenes as macrocyclic oligomers with 4–20 phenol units present two dened rims and a hydrophobic core. Since they show extensive host properties for small guest molecules, calixarenes are of high interest in supramolecular science. Due to their many unique properties, calixarenes are interesting candidates for the preparation of supramolecular polymers and nanostructures. Calixarenes are a...

The presence of specific hydrocarbon gas molecules in various types of water cavities in natural gas hydrates (NGHs) are governed by the relative stabilities of these encapsulated guest molecule-water cavity combinations. Using molecular quantum chemical dispersion-corrected hybrid density functional computations, the interaction (ΔE(host--guest)) and cohesive energies (ΔE(coh)), enthalpies, an...
