We have synthesised a neutral, water-soluble, Pt(II) complex able to aggregate more efficiently in aqueous solutions than in organic solvents. The aggregates are luminescent and are not quenched by molecular oxygen. Further, we have prepared phosphorescent hydrogels utilising host-guest interactions between cyclodextrins and the tetraethylene glycol tails of the Pt(II) complex. The soft assembl...

Chiral molecules possess enantiomers that have non-superimposable chemical structures but exhibit identical nuclear magnetic resonance (NMR) spectra. This feature prevents the use of NMR spectroscopic methods for determination enantiomeric excesses (ee) chiral molecules, using simple mixtures their enantiomers. Recently, however, it was reported addition a symmetrical prochiral molecule (a repo...

Polarimetry was used to investigate the binding abilities of a chiral calix[4]resorcinarene derivative, bearing L-proline subunits, towards a set of suitably selected organic guests. The simultaneous formation of 1:1 and 2:1 host-guest inclusion complexes was observed in several cases, depending on both the charge status of the host and the structure of the guest. Thus, the use of the polarimet...

The host-guest complexes of conjugated microporous polymers encapsulating C60 and dye molecules have been investigated systematically. The orientation of guest molecules inside the cavities, have different terms: inside the open cavities of the polymer, or inside the cavities formed by packing different polymers. The host backbone shows responsive dynamic behavior in order to accommodate the si...

A galactose-targeting supramolecular photosensitizer system DOX@GP5⊃NBSPD was constructed based on a host–guest inclusion complex, which could achieve the enhanced hypoxic-tumor therapeutic effectiveness by chemo-photodynamic combination.

Abstract Biomolecular systems show how host–guest binding can induce changes in molecular behavior, which turn impact the functions of system. Here we report an artificial system where dynamic adaptation during guest alters both host conformation and dynamics. The self-assembled cage employed here possesses concave walls a chirotopic cavity. Complementarity between curved surfaces fullerenes in...

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...

Rb-IV is the stable high-pressure phase of rubidium between 16 and 21 GPa. The structure of Rb-IV has long been known to be complex, but it is only recently that it has been solved as being an incommensurate host-guest composite structure, comprising a tetragonal host framework containing chains of ”guest” atoms that form structures incommensurate with the host along their common caxis. While s...

A range of solid-state NMR techniques is used to characterise a molecular host:guest complex consisting of a [5]polynorbornane bisurea host binding a terephthalate dianion guest. Detailed information is obtained on the molecular dynamics and associations from the point of view of both the host and guest molecules. The formation of the complex in the solid state is confirmed using (1)H 2D exchan...
