Two types of inclusion realised in the complexation between p-dimethylaminobenzoic acid and 2,6-dimethyl-β-cyclodextrin
Abstract
U.v. absorption, induced circular dichroism, and n.m.r. spectroscopic studies indicate that 2,6-dimethyl-β-cyclodextrin and p-dimethylaminobenzoic acid form an axial inclusion complex in water, but that they form an equatorial or lid-type supramolecular complex in chloroform.
