N2 - Two new GC stationary phases were prepared, one a side-chain liquid crystalline polysiloxane containing crown ether (PSC-11), and the other a new kind of side-chain crown ether (PSCP-11-15C-5) which has a similar structure to PSC-11. The main chromatographic characteristics, including efficiency, polarity and selectivity, were examined and compared. The mechanism of specific selectivity for positional isomer compounds based on the crown ether ring and liquid crystal is discussed.
