- 中文摘要: The retention behavior of five disubstituted benzene derivatives and two naphthalene derivatives is examined by using a chemically bonded b-cyclodextrin silica stationary phase with the moiety containing the s-triazine. The chromatographic results of five disubstituted benzene derivatives and two naphthalene derivatives show that effective separation is achieved on this stationary phase by high-performance liquid chromatography. The results of the present investigation indicate that the formation of inclusion complexes plays a dominant role in the separation mechanism. However, the selectivity can be significantly enhanced by the p-p interactions between the s-triazine ring of the chemically bonded b-cyclodextrin silica stationary phase and the aromatic ring of solutes. For example, the effective separation of the o-, m-, and p-toluidine isomers on this stationary phase with the moiety containing the s-triazine ring was better than on that of some b-cyclodextrin bonded stationary phases without the moiety containing s-triazine ring.
