Azacalix [4]arene betaine, which possesses intramolecular positive and negative charges, was synthesized. N,N'-Dimethylazacalix[4]arene was prepared by a simple procedure and subsequent N-quaternarization afforded the N,N,N',N'-tetramethyl diammonium compound. It was converted into the betaine struc
Addition of cyanuric chloride 2 (2,4,6-trichlorotriazine) to 4,6-diaminobenzene-1,3-disulfonic acid 1 gives a bis-triazine 3 which may be cyclised with diaminoarenes to yield water-soluble azacalix[4]arenes 5a-d. Alternatively, double substitution of chloride from the bis-triazine 3 yields new bis-t
