Since the first reports of periodic mesoporous organosilicas (PMOs) in 1999, this class of materials has attracted more and more attention. In general, such ordered templated mesoporous organosilicas are synthesized via the hydrolysis and co-condensation of bifunctional organosiloxane precursors, also referred to as bridged silsesquioxanes, in the presence of a structure directing agent (SDA) in either an acidic or alkaline environment. The uniqueness of PMO materials that combine the advantages of numerous organic functionalities with the outstanding characteristics of porous inorganic frameworks makes them a powerful toolbox for unlimited applications in multiple fields. Here, we will give a comprehensive review in this field by emphasizing the recent advances that have been achieved concerning their synthesis, morphology, functionalities, and applications mainly after 2014. In the final section, we pay a special attention to research that deals with the design, synthesis and application of a new family of PMOs denoted as hollow spherical and hollow/yolk shell periodic mesoporous organosilicas which display additional benefits as compared with traditional PMOs.

自 1999 年首次报道周期性介孔有机二氧化硅 (PMO) 以来，此类材料越来越受到关注。通常，在酸性或碱性环境中，在结构导向剂 (SDA) 存在下，通过双官能有机硅氧烷前体（也称为桥联倍半硅氧烷）的水解和共缩合来合成此类有序模板化介孔有机二氧化硅。PMO 材料的独特性将众多有机功能的优点与多孔无机骨架的突出特性相结合，使其成为可在多个领域无限应用的强大工具箱。在这里，我们将通过强调在其合成、形态、功能、
