Molecular Recognition by Steroid Cyclophane in Aqueous Solution and Synthetic Bilayer Membrane
A novel host named “steroid cyclophane,” a tetraaza[3.3.3.3]paracyclophane with four steroid moieties, was prepared, and its ability to recognize 8-anilinonaphthalene-1-sulfonate, a typical anionic guest with hydrophobic character, in aqueous media was examined in the presence and absence of synthetic bilayer membranes.
