摘　　要：笼形倍半硅氧烷(POSS)是基于化学键合作用而形成的分子内杂化体系,这种有着规整立体结构同时具有单纳米尺度的有机无机杂化分子引起了研究人员的广泛关注,独特的纳米笼形结构也为分子水平上改进高分子的科学研究提供了可能性。本文综述了多面体倍半硅氧烷(POSS)的结构、性能与合成方法,重点介绍了巯基POSS、金属杂化POSS、含氟POSS以及含卤代烷的POSS这四类新型官能团POSS,展望了POSS在有机无机杂化材料领域方面的巨大应用前景,并对POSS基材料的发展趋势和有待于进一步解决的问题进行了探讨。Polyhedral oligomeric silsesquioxane chemical bonding, and this single-nanometer scale is an intramolecular hybrid system based on the organic-inorganic hybrid molecular with a regular three-dimensional structure has attracted considerable attention in present researches, furthermore, its unique cage-shaped nanostructure also provides the possibility of the scientific researches to modify the polymers in molecular levels. The structures, properties, synthesis of polyhedral oligomeric silsesquioxane （POSS） will be reviewed in this paper. Among them, Metal- functionalized POSS,Thiolfunctionalized POSS,Fluorine-functionalized POSS and Alkyl halide-functionalized POSS will be mainly discussed,and then we will also forecast the great applied potentials of POSS in the area of organic inorganic hybrid materials and discuss its development trends and existent problems which are expected to be solved.
