| Abstract: | Two kinds of calix[4] arene functionalized(C[4]C5-PSO and C[4]TBE-PSO) were used as the stationary phases for capillary gas chromatography.The kinds of calix[4] arene functionalized were found to have unique selectivity for positional isomers of aromatic compounds.Thermodynamic parameters(△H,△S and △G) of these compounds were gained on two stationry phases.Molecular recognition and resolution mechanism about calix[4] arene functionalized were discussed form thermodynamic characteristics. |
