Abstract Cage-like organosiloxanes have proven to be ideal 3D building blocks for constructing unique classes of covalently-linked hybrid porous polymers with tunable structures and multifunctional properties for numerous applications. Since their discovery in 1990, hybrid porous polymers based on cage-like organosiloxanes (PCSs) have become an important subclass of porous materials and a relevant subject of contemporary research. Many PCSs with different structures and properties have been prepared by assembling a variety of monomers via multiple types of crosslinking reactions. Their general utility for adsorption, sensing, catalysis and drug delivery applications, etc. has been widely explored. Here, we review progress in PCSs since their inception covering monomer syntheses, material preparation methods, application explorations, discussing challenges and prospects for further development in this field.
