摘　　要：有机阳离子包覆多金属氧簇无机多阴离子形成的具有确定化学组成、两亲性核壳结构超分子复合物,具有易于调控和集成有机和无机组分结构与功能的特性.以此类复合物为预组装体的自组装和高分子功能杂化材料展现了一类具有多方面构筑超分子组装体的新型构筑基元体系.如何实现预组装体复合物在结构稳定、具有良好加工性基材中的组装和功能化成为这一领域的重要研究内容.本文系统地总结了基于此类超分子复合物的高分子纳米复合材料和溶液中组装方面的研究进展与发展趋势.Organic cation-encapsulated inorganic polyoxometalate polyanion supramolecular complexes exhibiting defined chemical composition and amphiphilic core-shell structure,which lead to tunable and synergetic structure and function of organic and inorganic components were summarized in this review.The self-assembly and polymer functional composite materials based on this type of complexes as pre-organization units were introduced to reveal a novel type of building block system for various supramolecular assemblies.The strategies to achieve the assembly and functionality in structure stable and well processable matrixes based on the pre-organization complexes were thought the key content of research in this field.It was believed highly important to assemble and functionalize the complexes in a well dispersed way in polymer materials.This review summarized the development of polymer nano-composite materials and assembly in solution based on the supramolecular complexes,and a perspective was anticipated.
