Four bis(guanidinium) receptors have been synthesized in which the guanidinium groups are spatially preorganized by an octahydroacridine (meso-3 and d,l-3) or hexahydrodicyclopenta[b,e]pyridine (meso-4 and d,l-4) spacer to complement a phosphodiester. These structures are designed to mimic the active site of staphylococcal nuclease and, thereby, form four hydrogen bonds to a bound phosphodiester with
