Ionosilica ionogels have been lately introduced as emerging all-ionic designer materials. They consist of an ionic liquid (IL) guest trapped within a solid ionosilica support host. In this work, we investigate the influence (i) nature and (ii) ionosilica/IL ratio on mobility confined IL. We report elaboration various via nonhydrolytic sol–gel process, using namely tris(3-(trimethoxysilyl)propyl...

We performed first-principles computations to investigate guest–host/host–host effects on the encapsulation of CO2 molecule in sII clathrate hydrates from finite-size clusters up periodic 3D crystal lattice systems. Structural and energetic properties were first computed for individual first-neighbors clathrate-like cages, where highly accurate ab initio quantum chemical methods are available n...

A sequence-controlled supramolecular copolymer was constructed by self-sorting assembly of metal coordination and two types host–guest interactions.

Mesoporous silica materials are ideally suited as host–guest systems in nanoscience with applications ranging frommolecular sieves, catalysts, nanosensors to drug-delivery-systems. For all these applications a thorough understanding of the interactions between the mesoporous host system and the guest molecules is vital. Here, we investigate these interactions using single molecule spectroscopy ...

Supramolecular materials based on host-guest interactions should exhibit high selectivity and external stimuli-responsiveness. Among various stimuli, redox and photo stimuli are useful for its wide application. An external stimuli-responsive adhesive system between CD host-gels (CD gels) and guest molecules modified glass substrates (guest Sub) is focused. Here, the selective adhesion between h...

The surface plasmon resonance (SPR) technique has been primarily used in the field of biology, in particular for the study of antibody-antigen interactions. Recently, polymers were introduced to form inclusion complexes. We describe here, a methodology based on surface plasmon resonance imaging to study water-resistant and reversible inclusion complexes using systems which are compatible with a...

We present a redox-responsive self-assembly based on a unimolecular platform. Three double-headed amphiphilic molecules composed of β-cyclodextrin (β-CD) and ferrocene (Fc) each with an alkyl chain as a linker (βCD-Cm-Fc, m = 2, 6, and 10) were synthesized, and their self-assembly behaviors were investigated. The molecules self-assembled into polydisperse micelles that transformed into vesicles...

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 ...

Molecular clips possessing U-shaped cavities have been functionalized on their convex side with long aliphatic tails. These molecules form dimers which self-assemble into malleable lamellar thin films. Upon addition of a guest (methyl 3,5-dihydroxybenzoate), a 1:1 host-guest complex is formed, which prohibits clip dimerization. As a result, the lamellar structure of the material is lost. Comple...
