Chiral biscavitand propellers: synthesis, conformations and multiple guest binding.
[structure: see text]. The synthesis and properties of molecules containing two cavitand bowls, with interbowl linkages comprising one carbon atom at various oxidation levels, are reported. A carbonyl-bridged biscavitand binds three CH2Cl2 molecules in the solid state through a helical conformation. Evidence for the same chiral conformation in the solution phase is presented.
