摘　　要：在纳米材料的应用过程中，纳米团簇或纳米粒子的组装将是非常关键的一步。纳米团簇的超分子化学组装方法可分为两类，即胶态晶体法和模板法。胶态晶体法是利用胶体溶液的自组装特性将纳米团簇组装成超晶格，可得到二维或三维有序的超晶格。模板法是利用纳米团簇与组装模板间的识别作用来带动团簇的组装，可应用的模板有固体膜、单分子膜、有机分子、生物分子等。其中，单分子膜模板是研究最多也是最为成熟的一种；生物分子间严密的分子识别功能使其成为非常有发展前途的组装模板，而且用生物分子模板有可能实现不同纳米团簇间的组装。The organization is a necessary step for the formation of devices from nanoclusters. The study of the organization of nanoclusters is very important for the development of nanotechnology. There are two kinds of methods for the supramolecular organization i.e. the formation of colloid crystals and the templated assembling. Two dimensional and three dimensional superlattices can be obtained with the colloid crystal method. The molecular recognition between template and nanoclusters is the impetus of templated organization. The templates described in this paper are the solid polymer membranes, monolayers, organic compounds, and biological molecules. The monolayer template has been studied extensively. Because of the more adequate and effective molecular recognition, the DNA molecule will be a prospective template for the organization of nanoclusters. The operated organization of different nanoclusters should come true with this method.
