Dative 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) are receiving an increasingly intensive interest, while the short of permanent porosity is an obstacle that must be overcome to guarantee their applications as porous materials. Here we report the first microporous crystalline framework BNOF-1 assembled through the sole monomers, which can be scalably synthesized by the cheap 4-pyridineboronic acid. The 2D networks of BNOF-1 were stacked in parallel to generate a highly porous supramolecular open framework, which possesses not only the highest BET surface area of 1345 m2 g−1 in all of the BNOFs but also the record-high uptake of C2H2 and CO2 in covalent organic framework (COF) materials to date. Dynamic breakthrough experiments demonstrated that BNOF-1 material can efficiently separate C2H2/CO2 mixtures. In addition, the network can be regenerated in organic solvents with no loss in performance, making it solution processable. We believe that BNOF-1 would greatly diversify the reticular chemistry and enlighten new avenues of BNOFs for application.
