The inclusion compound of β-cycloestrin (β-CD) with phosphatidlycholine (PC) was studied by elemental analysis of solid inclusion compound and UV-spectral of various mole ratios of β-CD/PC in H 20-MeOH solution.

Corrosion inhibition of copper by β- cyclodextrin and inclusion compound containing benzotriazde (BTA) in 0.

Molecules of cyclopentyl alcohol and ethyl alcohol are accommo- dated in the channel constructed by SL1 and SL2, respectively, thus forming the inclusion compounds.

It is reported that host molecules with chela shape, trans-9,10-di (1′-naphthy1)-phenanthrene-9,10-diol (1), can form the inclusion compounds with various small molecules containing nitrogen atoms, such as quinoline, isoquinoline, piperidine and dicyclohexylamine, while another compound, trans-9,10-di-benzyl-phenanthrene-9,10-diol (2) does not exhibit inclusion capability.

Cedrol, which has a spherical structure, can form inclusion compounds with some guest phenol typecompounds.

It could form the inclusion compounds with various small organic molecules such as DMF, DMSO, pyridine, piperidine, quinoline isoquinline.

The results showed that Q[6] interacted with guest BO with the ratio of 1 ∶1;Q[7] with the ratio of 2 ∶1 formed inclusion complex.

The experi-ental results reveal that a dumbbell shape inclusion complex of cucurbit[7]uril-guest was formed with a ra-io of 2∶1, and a bar shape inclusion complex of cucurbit[8]uril-guest was formed with a ratio of 1∶1.

Investigation of the interaction and structures of cucurbit[n]urils (n=6～8) with the title guests by using 1H NMR techniques and UV spectrum reveals that dumbbell shape inclusion complexes of cucur-bit[6]uril with bis{4-[(2,3 or 4-pyridyl)methyl-amino]-phenyl}methane were formed with a molar ratio of 2∶1, a.
