中文摘要：

利用线性溶剂化能相关,在相同色谱条件下,研究了对-叔丁基-杯[4]芳烃键合硅胶固定相与其它硅胶基质键合固定相的反相色谱行为.结果表明,对-叔丁基-杯[4]芳烃键合硅胶固定相和其它固定相在保留机理上有很大不同.控制溶质保留的两个主要因素不是溶质的体积和氢键受体碱性,而是溶质的过剩摩尔折光率和氢键给体酸性.r系数值较大说明π-π作用对溶质的保留贡献较为明显,说明该新固定相对高极化率溶质如稠环芳烃具有较高的选择性.

英文摘要：

The similarities and differences in retention characteristics of p-tert-Butyl-calix [ 4 ] arene-bonded and other three silica-based phases have been elucidated by linear solvation energy relationships under a common mobile phase. The p-tert-Butyl-calix [ 4 ] arene-bonded phase shows resemblances and differences to other silica-based reversed-phases. The retention of solutes on the phases is dominated by the solute excess molar refraction and hydrogen bond acidity instead of the solute size and hydrogen bond acceptor basicity. The coefficient is small and positive showed the new phase has bigger π-π interaction to solutes than that of all other phases, and relatively high selectivity to polyaromatic hydrocarbons.
