The application of host-guest inclusion complex formation to optical resolution is ideal. When an optically active host molecule includes one enantiomer of a racemic guest compound selectively, this inclusion phenomena can be used as a simple optical resolution method. Furthermore, this method might be applied to various neutral guest compounds. According to this idea, we tried to develop new optical resolution methods and established some new ones.

Host-guest inclusion complexes can be precipitated from aqueous solutions of pCD and BT or 3T (Scheme 1). Elementary analysis shows that stable complexes with 1 1 stoichiometry are obtained. In order to confirm the complex formation, fluorescence spectroscopy was used. The inclusion of a guest inside a cyclodextrin cavity produces a change in the electronic environm t of die guest. As a result, differences in the fluorescence spectra of free and CD-complexed monomer are expected. Fluoresc ce spectroscopy provides generally important information on die stoichiometry and equilibrium constants of inclusion... 

CB[n] nanoreactors have also been used to template the dimerization of peptides. Urbach et al. showed that CB[8] selectively recognizes N-temunal aromatic peptides, and that through the formation of 1 2 host-guest inclusion complexes, it templates the dimerization of these peptides [138]. This templating was shown via X-ray crystallography to occur via inclusion of the hydrophobic aromatic side chains inside the CB[8] cavity, while the proximal N-terminal ammonium groups are chelated by the portal carbonyls.

Inclusion complex formation with fluorescent NBD-guests corroborated internal hydrophobicity of /3-barrel hosts and potential for intratoroidal catalysis <2002CH18>. 

The formation of a one host-two guests inclusion-complex could proceed by way of two main mechanisms (/) dimerization of the guest, followed by inclusion and (2) stepwise inclusion of two guest molecules. In order to distinguish between these two possibilities, several temperature-jump relaxation kinetic studies have been carried us-...
