Abstract
Abstract The gas-liquid chromatographic separations of methyl-, ethyl-, and dimethylnaphthalene isomers on the nematic and supercooled regions of N,N′-bis( p -methoxybenzylidene)-α,α′-bi- p -toluidine are presented and compared with the results obtained on other materials. The unique selectivity of this liquid crystal, based upon differences in the molecular length-to-breadth ratio of the solute positional isomers, has enabled the complete separation of these naphthalene homologues.
