Understanding solvent effects on aryl CH···anion receptors is the next frontier in understanding the nature of this unique bond. Triazolophane macrocycles 22a and 22b showed a predictable 1/εr dependency in aprotic solvents but an unexpected linear decrease in anion association strength in protic solvents.
