One-Step Construction of Two Different Kinds of Pores in a 2D Covalent Organic Framework

Abstract: Covalent organic frameworks (COFs) are crystalline porous materials bearing microporous or mesoporous pores. The type and size of pores play crucial roles in regulating the properties of COFs. In this work, a novel COF, which bears two different kinds of ordered pores with controllable sizes: one within microporous range (7.1 Å) and the other in mesoporous range (26.9 Å), has been constructed via one-step synthesis. The structure of the dual-pore COF was confirmed by PXRD investigation, nitrogen adsorption-des… Show more

“…On the other hand, the use of macrocyclic host derivatives with a shallow rigid cavity as triformylcyclotrianisylene (f-CTV, 34), a derivative of the well-known cyclotriveratrylene (CTV), seems to stabilize the perfect eclipsed stack model rather than COFs based on planar motifs. The columnar stacking of crown CTV motifs avoids sliding between layers in CTV-COFs.…”

“…4,5,20,32 In general, COFs with hexagonal and tetragonal topologies are by far the most extensively investigated. 34 Finally, although many examples of 2D imine based COFs have been described, the development of three-dimensional (3D) analogues is still in its infancy. Hence, COFs with a trigonal topology have been rationally designed by using C 6 -symmetrical vertices as hexaphenylbenzene (HPB) and hexabenzocoronene (HBC), thus providing small pore sizes and high p-column densities.…”

“…POPs are considered as potential CO 2 sorbents due to their low density, high thermal and chemical stability, large surface area, tunable pore size and structure, and facilely tailored functionality. [41][42][43][44][45] The boronic acid condensation, 46-48 imine formation, 49,50 Suzuki coupling, 38 Friedel-Crafts alkylation, 51,52 Sonogashira reaction, 28,53 Yamamoto reaction 23,39 and so on, have well been established for the synthesis of POPs. However, most of POPs materials are typically amorphous but possess ultra-micropores because of disordered interpenetrations and highly cross-linked structures.…”
