摘      要：Nanostructures formed by functionalized gold nanoparticles(GNPs)were studied using X-ray diffraction(XRD).Two systems of such functionalized GNPs,one with gold core grafted by both ligand(rod-like liquid crystalline molecule)and co-ligand(alkylthiols)and the other one with only ligand grafted,were *** presence of ligands and co-ligands increases the mobility of GNPs and induces long-range ordered packing style with the change of *** both systems,functionalized GNPs form columns first and then pack on hexagonal *** is found that the correlation along column direction is dependent on surface conditions of GNPs,which is observed for system with only ligand *** on experimental results,size of gold core and number of ligand and co-ligand belonging to each gold core were *** intensities and electron density map of each structure were simulated,which are evidently similar to experimental ***,structure model was proposed and *** results help us to understand and control the way that organic molecules affect the organization of nanoparticles,and facilitate the design of new hybrid materials.
