| Research Abstract |
Multifunctionalized C_<2v>-cavitand was synthesized in six steps from a tetrabromo cavitand. A 1:1 mixture of the synthesized cavitand and Pt(dppp)(OTf)_2 in CDCl_3 or CD_2Cl_2 quantitatively self-assemble into a supramolecular hybrid capsule through hydrogen bond and metal-ligand coordination bond. Cavity of the capsule is filled with triflate ion and penetrated alkyl groups of ureides. The capsule encapsulates a neutral guest molecule such as 4, 4'-diiodobiphenyl with the assistance of an anion. Encapsulation complex was identified by NMR technic. The kinetics of guest exchange is controllable by the amounts and/or types of anions or other influences such as the polarity of the solvent.
