摘要研究了双液晶基元低摩尔质量有机硅氧烷液晶材料的反铁电行为。我们发现，该行为是由两个介晶之间的硅氧烷连接的构象控制。含有三个硅原子的硅氧烷链的弯曲构象似乎是将反铁电秩序强加给铁电材料的理想构象。
Abstract We investigate the interactions responsible for the antiferroelectric behaviour of bi-mesogen low molar mass organosiloxane liquid-crystal material. We find that the behaviour is controlled by the conformation of the siloxane link between the two mesogens. The bent conformation of the siloxane link containing three silicon atoms appears to be the ideal one to impose the antiferroelectric order to a material that would otherwise be ferroelectric.
