A. Casnati et al., SYNTHESIS OF WATER-SOLUBLE MOLECULAR RECEPTORS FROM CALIX[4]ARENES FIXED IN THE CONE CONFORMATION, Tetrahedron, 49(43), 1993, pp. 9815-9822
New water soluble hosts have been synthesized in good yields from cali
x[4]arenes fixed in the cone conformation. They are preorganized ditop
ic receptors which can be used for the selective recognition of metal
ions and neutral molecules in aqueous solution.
