Jk. Judice et al., SYNTHESIS AND BINDING-PROPERTIES OF A FAMILY OF POTENTIALLY CHIRAL SPHERANDS, Journal of the Chemical Society, Chemical Communications, (17), 1993, pp. 1325-1327
A new type of strongly binding and chiral spherand is reported,which i
s composed of a phenanthroline and four alkoxy benzene units incorpora
ted in 18-membered rings whose binding free energies and H-1 NMR spect
ra suggest the systems to be preorganized for complexation.
