Here, we report the first microporous crystalline framework, BNOF-1, that is assembled through sole monomers, which can be scalably synthesized by the cheap 4-pyridine boronic acid. The 2D networks of BNOF-1 were stacked in parallel to generate a highly porous supramolecular open framework, which possessed not only the highest BET surface area of 1345 m² g^-1 amongst all of the BNOFs but also features a record-high uptake of C₂H₂ and CO₂ in covalent organic framework (CChemical science533-539https://www.ebi.ac.uk/biostudies/studies/S-EPMC9847669biostudies-literatureDative B←N bonds based crystalline organic framework with permanent porosity for acetylene storage and separation.PMC9847669Hou LZhu ZDu FWang WLiu BWang GDWang YYWang LfalseDative B←N bonds based crystalline organic framework with permanent porosity for acetylene storage and separation.The utilization of dative B←N bonds for the creation of crystalline organic framework (BNOF) has increasingly received intensive interest; however, the shortage of permanent porosity is an obstacle that must be overcome to guarantee their application as porous materials.
