INTERACTIONS OF ORGANIC SOLVENTS WITH PHOTORESPONSIVE CAPPED CYCLODEXTRIN IN AQUEOUS SOLUTION

Azobenzene-capped β-cyclodextrin (I) forms complexes with organic solvents (methanol, DMSO, DMF, acetone and acetonitrile) according to 1:2 host/guest stoichiometry in its cis state, whereas exhibits nonstoichiometric behavior in its trans state.
