12. 6. Synthetic receptors, which take advantage of electrostatic interactions and can bind guests even in polar solvents, are reported in Ref. 2b.
13. 7. After uracil was adsorbed at 20°C, the mixture was heated to 70°C. About half of the adsorbed uracil was released to the aqueous phase, exactly as expected from an independent adsorption experiment at 70°C.
14. 8. Solid VDT did not adsorb uracil in water.
15. 9. The maximum uracil-binding capacity of PVDT(3.8μmol for 10 mg polymer), estimated from the Langmuir plot, corresponds to one binding site per 19 DAT residues.
16. 10. When 51.2 mg of styrene-VDT copolymer (containing 73 μmol of DAT residue as does 10 mg of PVDT) was contacted with uracil solution, 22% of initially charged uracil was adsorbed at 25°C. This value was almost the same as that of PVDT (see Table I). Moreover, the isotherm for the adsorption by the copolymer almost superimposed that for the adsorption by PVDT.
17. 11. Some contribution of stacking interaction in the guest binding was evidenced by the fact that 80% of xanthine, with respect to the initial concentration (0.1 mM), was adsorbed by PVDT at 25°C, whereas only 14% of adenine was adsorbed under identical conditions. A similar cooperation of hydrogen bonding and stacking interaction was indicated previously: (a) J.F. Constant, J. Fahy, and J. Lhomme: Tetrahedron Lett. 28, 1777 (1987).
