氟化四甘醇稳定的Au纳米粒子（FTEG-AuNPs）在甲醇（MeOH）和THF等极性有机溶剂中分散良好。发现在TEM网格和玻璃衬底上的FTEG-AuNP的流延膜形成高度有序的3D超晶格组装，而四乙二醇稳定的AuNP（TEG-AuNP）提供无定形AuNP聚集体。这些数据表明FTEG-AuNP表面上的氟特征对于纳米结构化组装是关键的。
Fluorinated tetraethylene glycol-stabilized Au nanoparticles (FTEG-AuNPs) were well-dispersed in general polar organic solvents, such as methanol (MeOH) and THF. The cast film of FTEG-AuNPs on a TEM grid and a glass substrate was found to form a highly ordered 3D-superlattice assembly, whereas tetraethylene glycol-stabilized AuNPs (TEG-AuNPs) provide an amorphous AuNP aggregation. These data indicate that the fluorine feature on the surface of the FTEG-AuNPs is critical for the nanostructured assembly.
