Palladium complexes of polycatenar 2,5-diphenylpyridine ligands were prepared in a two-stage reaction from (NH4)2[PdCl4]; their liquid crystal and emission properties are reported and discussed. For tetracatenar and hexacatenar derivatives, neither the ligand nor their complexes were liquid crystalline. The tricatenar ligand only showed a SmC phase identified by a Schlieren texture.

多链状 2,5-二苯基吡啶配体的钯配合物由 (NH 4 ) 2 [PdCl 4 ] 在两阶段反应中制备;报告和讨论了它们的液晶和发射特性。对于四链和六链衍生物,配体和它们的配合物都不是液晶的。三链配体仅显示由纹影纹理识别的 SmC 相。tricatenar 和 dicatenar 配体的钯化导致复合物显示出 SmA 相,其范围取决于配体。中间相的身份由小角 X 射线散射 (SAXS) 支持。所有配体和配合物都表现出发光特性,配合物的发射寿命表明不存在磷光。
