Pd. Beer et al., METAL, AMMONIUM AND ALKYL AMMONIUM CATION RECOGNITION BY A NOVEL CALIX[4]ARENEDIQUINONE CROWN-ETHER, Journal of the Chemical Society, Chemical Communications, (19), 1994, pp. 2207-2208
A novel calix[4]arenediquinone crown ether molecule L is prepared and
shown to strongly complex and electrochemically recognise Na+, K+, Ba2
+, NH4+ and BuNH(3)(+) guests; the X-ray crystal structure of the sodi
um complex of L is reported.
