Abstract

6-O-Modified β-cyclodextrins, such as heptakis(6-O-triisopropylsilyl)-β-cyclodextrin (TIPS-β-CD) and heptakis(6-O-tert-butyldimethylsilyl)-β-cyclodextrin (TBDMS-β-CD), formed 2:1 inclusion complexes with pyrene in benzene and cyclohexane with high association constants. The X-ray crystalline structure of the TIPS-β-CD-pyrene complex obtained from the benzene solution showed that one pyrene molecule was incorporated in the form of a sandwich-type complex with two benzene molecules within the cavity of the dimer formed by two TIPS-β-CD molecules.
