液晶配体修饰的片状金纳米粒子的晶格行为：计算机模拟研究
Gelation of patchy gold nanoparticles decorated by liquid-crystalline ligands: computer simulation study
摘要：
我们考虑用液晶配体修饰的片状金纳米粒子。讨论了两个、三个、四个和六个对称排列的配位体的情况，以及它们的赤道和均匀排列的情况。装饰纳米粒子的溶液被认为是在一个平面孔与固体壁和内部填充极性溶剂。由于强的液晶相互作用，配体在纳米颗粒之间形成物理交联，将溶液变成凝胶状结构。每次从纳米颗粒的新鲜平衡分散状态开始重复进行甘精胰岛素。的凝胶化动力学和网络特性的凝胶的范围内进行检查，取决于斑片装饰和溶液密度的类型。重点是给出了一个凝胶催化应用的适用性
英文摘要：
We consider patchy gold nanoparticles decorated by liquid crystalline ligands. The cases of two, three, four and six symmetrically arranged patches of ligands are discussed, as well as the cases of their equatorial and uniform arrangement. A solution of decorated nanoparticles is considered within a flat pore with the solid walls and the interior filled by a polar solvent. The ligands form physical crosslinks between the nanoparticles due to strong liquid crystalline interaction, turning the solution into a gel-like structure. Gelation is done repeatedly starting each time from freshly equilibrated dispersed state of nanoparticles. The gelation dynamics and the range of network characteristics of gel are examined, depending on the type of patchy decoration and the solution density. The emphasis is given to the suitability of a gel for catalytic applications
