“…Post‐synthesis hypercrosslinking of styrenic PHs via Friedel‐Crafts reactions has been used to achieve PHs with specific surface areas as high as 1600 m 2 /g . BCP self‐assembly, with semi‐crystalline endblock domains and microphase‐separated midblock domains, has been observed within the walls of a PH based on a methacrylated triblock copolymer as the only monomer .…”

Porous polymers have been evolving continuously since the introduction of foam rubber in 1929. Today, pore diameters ranging from sub‐nanometre to millimetre can be generated controllably. Cutting‐edge porous polymers are now being applied at the forefront of critical problems with societal and environmental impact including advanced systems for biomedicine, water purification, energy storage, and gas purification and storage. The commonly‐used pore generation approaches include macromolecular design, self‐assembly, phase separation, solid and liquid templating, sol‐gel formation, and foaming. In each, The Chemistry of Polymers, both the polymerization chemistry and the macromolecular structural chemistry, must be applied advantageously to generate the empty volume within the polymer and then fix it in place. This essay will traverse the various pore size scales, describing the chemistries involved and discussing their implications.

“…The main focus of the papers in the next section of this special issue is the preparation of advanced materials, their characterization, and fundamental structure-properties studies. The paper by Silverstein [74] describes the preparation of materials with hierarchical porous structures and the effect of reaction conditions on the porosity. Sheiko [75] presents a methodology that leads to materials with triple shape memory, in which various shapes may be encoded at the same temperature.…”

“…However, these methods have certain limitations, for example hard template methods need tedious synthetic procedures to introduce and remove hard template, and soft template methods require either low temperature treatment or an essential activation step to generate porosity. Recently, porous organic polymers have received more attention to make porous carbon materials, utilizing their highly porous structures . For example, Wu and co‐workers reported the synthesis of microporous carbon nanospheres via molecular‐scale interfacial engineering using organic/inorganic hybrid molecules as the building block .…”

“…Dai and co‐workers designed another route for synthesizing metal‐incorporated C‐covalent organic polymers (COP) materials based on the 2D COPs . Israel et al synthesized porous carbons with hierarchical porous structures using poly high internal phase emulsions (PolyHIPEs) as precursor . This method can avoid the collapse of nanostructures during pyrolysis and thus retain the porous structures without applying additional time consuming procedures or chemically removing of templates .…”

Porous carbon materials prepared from the porous organic polymers are currently the subject of extensive investigation. On the basis of their interesting applications, it is highly desirable to develop new synthetic methodologies to obtain carbon materials with controllable pore size and morphology. Herein, a facile synthesis of hollow microporous carbon spheres (HCSs) from hollow microporous organic capsules (HMOCs) with a good control over the pore morphology, hollow cavity, and the shell thickness is reported. The highly porous hollow carbon spheres are prepared by the pyrolysis of HMOCs-based microporous polymers. The synthetic parameters, such as hypercrosslinking and pyrolysis conditions, are optimized to modify the porous structures and the properties. The morphology and porosity as well as energy storage applications of the microporous structures HCSs, derived through a combination of divinylbenzene-crosslinking and micropore-generating hypercrosslinking, are discussed. These findings provide a new benchmark for fabricating well-defined HCSs with great promise for various applications.
