Different gold microstructures have been synthesized by using supramolecular gold(I) organometallic compounds as templates and Ag nanoparticles as reducing agents. The use of fibers resulting from supramolecular assemblies of neutral gold(I) compounds gives rise to the formation of microrods. The use of supramolecular assemblies from ionic molecules results in spherical or square-based prism gold microstructures, depending on the shape of the supramolecular gold(I) precursor assembly. In addition to temperature and reaction time, solvents exert a strong influence on the formation and morphology of gold structures, as borne out by the example that well-defined star-like morphologies have been obtained in chloroform.

亲金装配体对Gold（0）结构的容易形态控制

通过使用超分子金（I）有机金属化合物作为模板和银纳米颗粒作为还原剂，合成了不同的金微结构。由中性金（I）化合物的超分子组装产生的纤维的使用引起微棒的形成。取决于超分子金（I）前体组件的形状，使用来自离子分子的超分子组件会导致球形或方形的棱镜金微结构。除温度和反应时间外，溶剂还对金结构的形成和形态产生很大影响，如以下实例所证明的那样：在氯仿中已获得定义明确的星形形态。
