Host–Guest Systems An Unstable Ligand-Unsupported Cu Dimer Stabilized in a Supramolecular Framework**
The attractive interactions that exist between d “closedshell” elements of Group 11 have received extensive attention. 2] The term “aurophilicity” has been coined to describe the Au Au bonding interactions that are evident in many molecular and solid-state structures and have been attributed to correlation and relativistic effects. However, relativistic effects cannot be invoked for Cu···Cu int...
متن کاملCyclodextrin-based supramolecular nanoparticles stabilized by balancing attractive host-guest and repulsive electrostatic interactions.
Multicomponent, negatively charged supramolecular nanoparticles (SNPs) were formed by multivalent host-guest interactions without the need of a stopper in water and in PBS. Their size and stability are controlled owing to a balance of forces between attractive supramolecular and repulsive electrostatic interactions.
متن کاملHost-guest chemistry of tolbutamide.
The molecular recognition features of tolbutamide with four synthetic hosts have been studied by means of NMR titrations, NOESY experiments and Monte Carlo (MC) conformational search. The interaction strength and the most probable structure reveal new insights on the recognition phenomena of this urea derivative in comparison with close related compounds.
متن کاملReversible guest exchange mechanisms in supramolecular host-guest assemblies.
Synthetic chemists have provided a wide array of supramolecular assemblies able to encapsulate guest molecules. The scope of this tutorial review focuses on supramolecular host molecules capable of reversibly encapsulating polyatomic guests. Much work has been done to determine the mechanism of guest encapsulation and guest release. This review covers common methods of monitoring and characteri...
متن کاملHybrid host-guest complexes: directing the supramolecular structure through secondary host-guest interactions.
A set of four hybrid host-guest complexes based on the inorganic crown ether analogue [H12W36O120]12- ({W36}) have been isolated and characterised. The cluster anion features a central rigid binding site made up of six terminal oxygen ligands and this motif allows the selective binding of a range of alkali and alkali-earth-metal cations. Here, the binding site was utilised to functionalise the ...
