SYNTHESIS OF MONOAMIDE-CUCURBITURIL, OLIGOAMIDE-CUCURBITURIL AND POLYAMIDE-CUCURBITURIL ROTAXANES

Mono-, oligo- and polyamide rotaxanes with the macrocycle cucurbituril are synthesized easily with high yields by interfacial condensation. The complex of cucurbituril with 1,6-hexanediammonium ion is used as p reorganized structure. With different acid and diacid chlorides a grea t variety of amiderotaxanes and polyrotaxanes can be synthesized. The characterization is difficult due to the low solubility of cucurbituri l and rotaxanes. But with the methods of IR, DTA, H-1 NMR and elementa l analyses, the existence of the rotaxanes is shown.
