报道了液晶中第一个单金刚石立方相。这种具有F d 3 m空间群的骨架结构是通过具有燕尾侧链的bola两亲物的自组装形成的。它由π共轭对三联苯棒束组成，这些棒通过四面体四向结处的氢键球融合成无限网络。我们还提出了一个定量模型有关的分子结构的空间填充要求的六个可能的双连续立方相，即单和双网络版本的螺旋，钻石，和“水管工的噩梦”。
The first single-diamond cubic phase in a liquid crystal is reported. This skeletal structure with the F d 3 ‾ m space group is formed by self-assembly of bolaamphiphiles with swallow-tailed lateral chains. It consists of bundles of π-conjugated p-terphenyl rods fused into an infinite network by hydrogen-bonded spheres at tetrahedral four-way junctions. We also present a quantitative model relating molecular architecture to the space-filling requirements of six possible bicontinuous cubic phases, that is, the single- and double-network versions of gyroid, diamond, and "plumber's nightmare".
