18. In an earlier attempt to bring together four identical molecules into a self-assembled tetramer, urea functions were used as the exclusive hydrogen-bonding units, but this formed an extended ribbon structure in the solid state [X. Garcías, L. M. Toledo, J. Rebek Jr., Tetrahedron Lett. 36, 8535 (1995)]. For a planar tetrameric assembly related to G-quartets, see R. G. Barr and T. J. Pinnavaia, J. Chem. Phys. 90, 328 (1986).

28. These compounds were prepared by monoalkylation of the corresponding urea and cyclic sulfamide with 1-bromodecane. The presence of the long alkyl chain is necessary for good solubility in noncompetitive solvents.
