Abstract
A metallo-cavitand (1-2Pd) showed unprecedented binding selectivity and sequestration of p-functionalized toluene isomers in water. The host-guest complexation was studied using 1H and COSY NMR methods and xylene-isomer complexes were examined by using DFT calculations. A liquid-liquid extraction scheme was developed for the separation of p-functionalized toluenes.
