报道了对稳定的、自由悬浮的液晶链的观察。六正十二酸三苯液晶可以拉伸成直径约为1 μm的链，并沿链轴排列成柱状的盘状分子。在d1相（T< 110℃），分子相对于链轴倾斜，倾斜方向表现为一维向列场，被相对于柱晶格的简并稳定位置之间的方向跳跃所中断。
Observations of stable, freely suspended liquid-crystal strands are reported. Liquid crystals of triphenylene hexa-n-dodecanoate can be stretched into strands of diameter≳ 1 μm, with the disk-shaped molecules arranged into columns along the strand axis. In the D 1 phase (T< 110 C) the molecules are tilted with respect to the strand axis, the tilt orientation behaving as a one-dimensional nematiclike field, interrupted by jumps in orientation between degenerate stable positions relative to the column lattice.
