Lid-type inclusion of pyrene-1,3,6,8-tetrasulphonate anion by β-cyclodextrin
Abstract
U.v. absorption and induced circular dichroism studies have indicated a new type of inclusion behaviour (‘lid-type’) in cyclodextrin–arene 1 : 1 host–guest complexes exemplified by the pyrene-1,3,6,8-tetrasulphonate–β-cyclodextrin complex.
