我们已经建立了由X射线衍射，锥形分子可以形成相对有序的柱状中间相。研究了四种中间相。其中三个具有平行柱中的经典二维组织，而第四个显示出准晶体结构：3D有序发生在围绕圆锥形核心的长链烷烃链的水平上，尽管这些链处于“熔融状态”。中间相的形成assez ordonnees
We have established by X-ray diffraction that cone-shaped molecules can form relatively well ordered columnar mesophases. Four mesophases have been studied. Three of them have the classical two-dimensional organization in parallel columns while the fourth one shows a quasi-crystalline structure: 3D-ordering takes place at the level of the long paraffinic chains which surround the conical core despite the fact that the chains are in a «molten state» Etude sur 3 hexaesters de cyclotricatechylene.
