用偏光显微镜研究了圆盘状液晶三苯(C8OBT)在烷硫醇和不对称二硫自组装单层(SAMs)表面的取向行为。C8OBT的盘状向列相(ND)和矩形柱状相(color)表现出不同的排列行为,这取决于sam的元素。C8OBT在色相烷烃硫醇SAM上呈扇形织构,而在不对称二硫化物SAM上呈平面排列。
Alignment behavior of a discotic liquid crystalline triphenylene (C8OBT) on substrates coated with self-assembled monolayers (SAMs) of alkanethiol and asymmetrical disulfide was investigated by polarized microscopy. Discotic nematic (ND) and rectangular columnar (Colr) phases of C8OBT shows a different alignment behavior depending on the element of SAMs. C8OBT exhibits a fan-shaped texture on an alkanethiol SAM in Colr phase, while it shows a planar alignment on a SAM of asymmetrical disulfide.
