通过热力学，光谱和结构的研究，熔融状态的烷基链在SmE相，这是最接近有序的结晶相的液晶中间相，已建立在一个棒状介晶nPA。结合另一种棒状介晶nTCB的SmE相的相同结论，可以得出结论，连接在棒状核的末端的烷基链在任何液晶中间相中都是熔融的。热力学的影响进行了简要讨论。
Through thermodynamic, spectroscopic, and structural studies, the molten state of the alkyl chain in SmE phase, which is the liquid-crystalline mesophase closest to an ordered crystalline phase, has been established in a calamitic mesogen nPA. Combining the same conclusion for the SmE phase of another calamitic mesogen nTCB, it is concluded that the alkyl chain attached at end(s) of a rod-like core is molten in any liquid-crystalline mesophase. The thermodynamic implications are briefly discussed.
