Organically modified cubic polyhedral oligomeric silsesquioxanes (POSS) have attracted increasing attention in the design of novel functional hybrid materials for applications such as porous materials, liquid crystals, semiconductors, high-temperature lubricants, fuel cells, and lithium batteries. The nanosized POSS moiety can be conveniently modified on the periphery with a variety of functional groups to lead to hybrid materials with desired functions. In addition, suitable mono-functionalized POSS derivatives can be incorporated into polymers as side chains via various synthetic strategies to offer a wide class of functional polymeric materials with tunable physical properties for targeted applications. In this Focus Review, we aim to summarize the recent developments on the chemistry and applications of POSS-based molecules and polymers. Moreover, the properties as well as assembly behavior of the POSS-based functional hybrid materials will be reviewed, and the relationship of the performance of the hybrid materials with the intrinsic nature of the POSS unit will be addressed.
有机改性的立方多面体低聚倍半硅氧烷（POSS）在新型功能杂化材料的设计中受到越来越多的关注，这些材料可应用于多孔材料、液晶、半导体、高温润滑剂、燃料电池和锂电池等领域。纳米尺寸的POSS部分可以方便地在外围用各种官能团进行改性，从而得到具有所需功能的杂化材料。此外，合适的单官能化POSS衍生物可以通过各种合成策略作为侧链掺入聚合物中，以提供一大类具有可调物理性质的功能聚合物材料，用于特定应用。在本聚焦综述中，我们旨在总结基于POSS的分子和聚合物在化学和应用方面的最新进展。此外，还将综述基于POSS的功能杂化材料的性能以及组装行为，并探讨杂化材料性能与POSS单元固有性质之间的关系。
