with their related complexes with silver dodecylsulphate and silver triflate. The single crystal structures of one ligand and two complexes are reported. While none of the complexes of the 2-stilbazoles is liquid-crystalline, several complexes of the 3-stilbazoles show columnar mesophases as characterised by polarised optical microscopy and X-ray diffraction. The liquid crystal phase behaviour is compared
据报道2-和3-苯乙烯基唑的3,4-二烷氧基和3,4,5-三烷氧基衍生物的合成以及它们与十二烷基硫酸银和三氟甲磺酸银的相关配合物。报道了一种配体和两种配合物的单晶结构。虽然2-苯乙烯基唑的配合物都不是液晶的,但是3-苯乙烯基唑的几种配合物显示出柱状中间相,如通过偏振光学显微镜和X射线衍射所表征的。将液晶相行为与母体4-苯乙烯基唑衍生物的相行为进行比较。
