摘要

The synthesis of micro and mesoporous organic materials with well-defined pore size and structure is currently a major challenge in materials science. Because of their purely organic nature, such systems are expected to introduce new opportunities that expand on those of their well-known inorganic analogues. Since the pioneering work on polystyrene-derived resins, macroporous polymers (pore diameter >50nm) became a well-established family of porous materials. Here, the porosity arises mainly from microphase separation during the polymerization reaction. On the other hand, studies on hyper-crosslinked polystyrene networks further confirmed that it is also possible to generate microporous (pore diameter <2 nm) organic materials with high surface area. Owing to several recent studies, these findings were extended to different type of polymers, from polymers with intrinsic microporosity to covalent organic frameworks.
