Inclusion Compounds of Dehydrocholic Acid with Solvents
The host-guest inclusion of various organic solvents within dehydrocholic acid has been studied and the selectivity of enclathration determined by competition experiments.
متن کاملA new polymorph and two inclusion compounds of 9,9'-spirobifluorene.
Two new inclusion compounds of 9,9'-spirobifluorene (SBF) incorporating benzene [(I), C25H16.C6H6] and biphenyl [(II), C25H16.C12H10], and a new polymorph of SBF [(III), C25H16] are reported. All three exhibit C-H...pi(arene) hydrogen bonds between adjacent SBF molecules. Compound (II) also contains biphenyl C-H to SBF pi-arene interactions. Collectively, hydrogen bonding gives rise to a chain ...

متن کاملInclusion compounds of lankacidin-group antibiotics with cyclodextrins.
Lankacidin-group antibiotics formed inclusion compounds with beta-cyclodextrin in molar ratios of about 1:1. These compounds showed remarkably improved water-solubility and stability in aqueous solutions. The structure of the inclusion compounds of lankacidin A is proposed based on the facility of their inclusion with beta-cyclodextrin and the results of 1H NMR spectral studies.
متن کاملThiourea and Thiourea Inclusion Compounds. A N NQR Investigation
A reinvestigation of the nitrogen-14 NQR in thiourea has permitted to record, apparently for the first time, the resonances above 169 K. The first order and second order of the transitions at 169 K and 202 K, respectively, appear clearly from the temperature dependence of the resonance frequencies; the modulated structure, incommensurate or commensurate, is also seen on the N NQR spectrum. This...
