“…[10] Highly porous carbons have been produced in the past with the use of KOH as a chemical activating agent, through precursors including linear polymers, [11,12] carbon nanotubes, [13] and graphene oxide. [14] A number of microporous solids have been precursors for carbonaceous materials with advanced properties, including zeolitic imidazolate frameworks (ZIFs), [15] metalorganic frameworks (MOFs), [16] porous aromatic frameworks (PAFs), [17] conjugated microporous polymers (CMPs), [18] and hypercrosslinked polymers (HCPs). [19] The choice of precursor material can affect the functionality in the resultant carbons.…”

“…In the low pressure range, polycarbazole skeleton exhibits favorable interaction with the H 2 molecules, suggesting the importance of ultramicropore structure and electron-rich system for gas adsorption which is the unique nature of conjugated polymers compared with other porous organic polymers. The H 2 uptake of P-TCz network is among the highest reported CMPs, such as PAF-1 (1.5 wt%) [21], CMP-2 (0.91 wt%) [15], polyanilines (0.85 wt%) [22], and PPN-3 (1.58 wt%) [23].…”

a b s t r a c tThree carbazole based building blocks with similar propeller-like steric configuration are designed and synthesized. The polycarbazole networks P-4, 4 0 -biscarbazolyl-phenyl (P-BCz), P-tetracarbazolyl-pdifluorobenzene (P-TCz) and P-hexacarbazolyl-phenyl (P-HCz) are obtained with high surface areas and uniform ultramicropores. The aggregation morphologies of networks vary from regular spherical particles, ribbon-like structure to large lamellar structure as the number of carbazole increased around the benzene ring. The networks P-TCz, with four carbazole decorating on the benzene ring, have the largest surface area and highest gas uptake ability among the three networks. However, the CO 2 and CH 4 isosteric enthalpies increased linearly with increasing the number of carbazole. The networks P-HCz with six carbazole show the excellent CO 2 /N 2 separative capacity (107 at 273 K, and 127 at 298 K), which is among the highest reported about CO 2 separation using organic pore networks. Fine designing and tailoring the topological structure of monomer can control the adsorption properties and optimize the gas uptake performance.

Synthesis and Applications of Porous Organic Cages

Solids composed of shape-persistent organic cage molecules are an emerging class of porous materials. Research in this area has recently progressed from understanding the nature of porosity in these materials to finding applications suited to their unique properties. For example, given that the cages are held together in the solid state by relatively weak (compared to covalent interactions) dispersion forces, the resultant materials are structurally flexible and thus physical properties, such as porosity, that can be modulated according to the adsorbate to which it is exposed. Moreover, discrete cages are soluble and can thus be reprecipitated as structural polymorphs that possess different properties, or processed into thin layers or composite materials such as mixed matrix membranes. In this review, we highlight the synthetic strategies that have been employed to produce porous organic cages and discuss recent advances in design concepts that have led to ultraporous solids. We will also canvass recent applications of these materials and posit potential areas of development.
