Four new opticallyactive cyclophanes with apolar cavities shaped by the major grooves of the 2,2′, 6,6′- nd 2,2′, 7,7′-tetraoxa-1,1′-binaphthyl units were prepared for the inclusion complexation of naproxen derivatives in aqueous solution. Macrocycles formed by one diphenylmethane and one binaphthyl spacer give stronger binding and, unexpectedly, a higher degree of chiral recognition than cyclophanes
