Metal, ammonium and alkyl ammonium cation recognition by a novel calix[4]arenediquinone crown ether
Abstract
A novel calix[4]arenediquinone crown ether molecule L is prepared and shown to strongly complex and electrochemically recognise Na+, K+, Ba2+, NH4+ and BuNH3+ guests; the X-ray crystal structure of the sodium complex of L is reported.
