摘要：

New salt binders whose ligands were composed of four aromatic sp? nitrogens and purely based on a cavitand were efficiently synthesized and characterized. Imidazolylcavitand 3 showed high affinity for picrate salts (-Delta G(degrees)=7.0 similar to 11.0 kcal mol(-1)) and pyrazolylcavitand 4 showed unusual high selectivity for silver picrate.
