Solvent-gelator interactions play a key role in mediating organogel formation and ultimately determine the physico-chemical properties of the organogels and xerogels. The ethanol organogels of 1,4-bis[(3,4,5-trihexyloxy phenyl)hydrazide]phenylene (TC6) were investigated by FT-IR, Raman and fluorescence spectra, and XRD, and it was confirmed that the intermolecular interaction and aggregation structure of TC6 ethanol organogels were quite different from those of xerogels. Simultaneously, unprecedented phase transition from organogel to suspension upon heating was observed in ethanol organogel, and the suspension phase exhibited lytropic liquid crystalline behaviour with a rectangular columnar structure. This study may open the possibility to design new gelators with a new dimension of versatility.
溶剂-凝胶剂相互作用在介导有机凝胶形成过程中起着关键作用，并最终决定有机凝胶和干凝胶的物理化学性质。通过傅里叶变换红外光谱（FT-IR）、拉曼光谱、荧光光谱和X射线衍射（XRD）对1,4-双[(3,4,5-三己氧基苯基)酰肼]亚苯基（TC6）的乙醇有机凝胶进行了研究，证实了TC6乙醇有机凝胶的分子间相互作用和聚集结构与干凝胶有很大不同。同时，在乙醇有机凝胶中观察到了加热时从有机凝胶到悬浮液的前所未有的相变，并且悬浮相表现出具有矩形柱状结构的溶致液晶行为。这项研究可能为设计具有新的多功能维度的新型凝胶剂开辟可能性。
