Polyhedral oligomeric silsesquioxanes (POSS) and hybrid organo-halide perovskites are two important types of hybrid nanoscale frameworks with great potential in materials chemistry. Both are currently under intensive investigation for a wide range of possible applications. Recent results suggest that POSS can be attractive passivating and structure-controlling agents for perovskite materials. In this review, we present the importance of POSS in engineering the structures of inorganic cesium-halide perovskites CsPbX (X = Cl, Br, I) to create a new class of hybrid derivatives with improved properties. The combination of these two components can be an effective strategy for controlling the perovskite crystallization process. In addition, passivation of surface defects/bulk and the engineering of energy and optoelectronic properties of perovskite-based materials can be achieved following this method. In this minireview, we summarized the existing literature reports on the structural specificity and properties of hybrid POSS perovskites.
多面体低聚倍半硅氧烷(POSS)和有机卤化物杂化钙钛矿是材料化学中具有巨大潜力的两种重要的杂化纳米级框架类型。目前,它们都在针对广泛的可能应用进行深入研究。最近的结果表明,POSS对于钙钛矿材料而言可能是有吸引力的钝化剂和结构控制剂。在本综述中,我们阐述了POSS在设计无机卤化铯钙钛矿CsPbX(X = Cl、Br、I)结构以创建一类具有改进性能的新型杂化衍生物方面的重要性。这两种成分的组合可能是控制钙钛矿结晶过程的有效策略。此外,通过这种方法可以实现对基于钙钛矿材料的表面缺陷/体相的钝化以及能量和光电性能的设计。在本微型综述中,我们总结了关于杂化POSS钙钛矿的结构特异性和性能的现有文献报道。
