1984年葛海霖等人首先提出用溶质在不同相上的保留指数之差值(ΔJ~(T_0)=I_液晶~(T_0)-I_液~(T_0))来反映固定液的特殊液晶效应。1982年Witkiewicz提出了芳烃异构体在液晶固定液上的溶解焓差Δ(ΔH)和溶解熵差Δ(ΔS)值。1986年金鑫荣等采用同分异构体(如蒽与菲)作为探测物,测定在液晶固定液上的Δ(ΔH)和Δ(ΔS),并把它与微观物理量联系起来。本文在原二文的基础上,研究了不同类型溶质在液相(L)和液晶相(LC)上的Δ(ΔH)_(L-LC)和Δ(AS)_(L-LC)值,阐明ΔI~(T_0)的宏观与微观的物理意义。
In 1984, Ge Hailin and others first proposed that the difference of retention index (ΔJ ~ (T_0) = I_LCD_ (T_0) -I_LCO_ (T_0)) of solutes on different phases should reflect the special liquid crystal effect . In 1982, Witkiewicz proposed the enthalpy difference Δ (ΔH) and the entropy difference Δ (ΔS) values of aromatic isomers on the liquid crystal fixing solution. In 1986, Jin Xinrong and other isomers (such as anthracene and phenanthrene) as a probe, measured in the liquid crystal fixative Δ (ΔH) and Δ (ΔS), and its micro physical quantities linked. Based on the original two papers, the Δ (ΔH) _ (L-LC) and Δ (AS) _ (L-LC) values of different types of solutes on the liquid phase (L) and the liquid crystal phase (LC) The physical meaning of macro and micro of ΔI ~ (T_0) is clarified.
