An amphiphilic calix[4]arene with sulfonate groups on the lower rim has been investigated as a buffer additive for separation of positional isomers by capillary electrophoresis. Addition of the compound to the run-ning buffer led to successful separation of positional isomers of nitrophenols, dinitrobenzenes, and benzenediols. Association constants between the calixarene and the analytes indicated that size-selective host–guest inter-actions between them played a prominent role in determining the separation behavior.
