Molecules in Confined Spaces: Reactivities

The above concept of orienting molecules within confined spaces has been extended to cavitand type host systems such as cyclodextrins (CD), cucurbiturils (CB), calixarenes (CA), Pd nanocage and cavitand octa acid . These water soluble host systems are open at more than one end and they in principle, similar to micelle, could expose a guest molecule to hydrophobic–hydrophilic interface.

Water-soluble cavitands promote hydrolyses of long-chain

Molecules in confined spaces behave differently from those in bulk solution and a number of container (host) compounds have been developed to exploit the differences. In aqueous media, hydrophobic forces can drive binding of guests into the limited space of container hosts, and flexible guests assume shapes congruent with the container’s space. Long-chain hydrocarbons take

Self‐Assembly of 2,8,14,20‐Tetraisobutyl‐5,11,17,23

Chemistry in confined space in our group concerns the chemistry of host-guest systems, with a special attention paid to the synthesis and applications, mainly in sensing and supramolecular catalysis, of container-shaped molecular hosts derived from cryptophanes, (hemi)cryptophanes and cavitands.

Chemistry in confined space through the eyes of surface

FUNCTIONAL CAVITANDS. Cavitands are synthetic molecules with a permanent concave shape that can accommodate smaller molecules or ions inside. The encapsulation of a molecule in the confined space of cavitands has dramatic consequences for the reactivity of the bound species, and these effects can be harnessed to develop enzyme-like reactivity and catalysis.

Photo-Fries rearrangement of aryl acetamides

The use of confined assemblies, such as zeolites, micelles, polyolefin films, cavitands, dendrimers, etc., can be considered as strategies devised to control product distributions in photochemical reactions. 1 The restricted mobility within the hydrophobic cores of these confined assemblies limits the tendency of radicals, radical cations, or
