Hexagonal packing lattice formed by functionalized gold nanoparticles
文献摘要：
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 studied.The presence of ligands and co-ligands increases the mobility of GNPs and induces long-range ordered packing style with the change of temperature.In both systems,functionalized GNPs form columns first and then pack on hexagonal lat-tice.It is found that the correlation along column direction is dependent on surface conditions of GNPs,which is observed for system with only ligand grafted.Based on experimental results,size of gold core and number of ligand and co-ligand belonging to each gold core were calculated.Diffraction intensities and electron density map of each structure were simulated,which are evidently similar to experimental ones.Finally,structure model was proposed and discussed.The 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.
