Ortho-Alkoxy-benzamide Directed Formation of a Single Crystalline Hydrogen-bonded Crosslinked Organic Framework and Its Boron Trifluoride Uptake and Catalysis. | LitMetric

AI Article Synopsis

  • Boron trifluoride (BF) is a corrosive gas used in various industries, making its safe handling a priority by utilizing porous materials for storage.
  • A new hydrogen-bond crosslinked organic framework (H OF-50) was developed, showcasing a high BF uptake capacity of 14.2 mmol/g due to its specialized structure and properties.
  • This framework not only allows for reversible BF uptake but also enhances the cationic polymerization of vinyl ethers, resulting in better-quality polymers with higher molecular weights and improved consistency.

Article Abstract

Boron trifluoride (BF ) is a highly corrosive gas widely used in industry. Confining BF in porous materials ensures safe and convenient handling and prevents its degradation. Hence, it is highly desired to develop porous materials with high adsorption capacity, high stability, and resistance to BF corrosion. Herein, we designed and synthesized a Lewis basic single-crystalline hydrogen-bond crosslinked organic framework (H OF-50) for BF storage and its application in catalysis. Specifically, we introduced self-complementary ortho-alkoxy-benzamide hydrogen-bonding moieties to direct the formation of highly organized hydrogen-bonded networks, which were subsequently photo-crosslinked to generate H OFs. The H OF-50 features Lewis basic thioether linkages and electron-rich pore surfaces for BF uptake. As a result, H OF-50 shows a record-high 14.2 mmol/g BF uptake capacity. The BF uptake in H OF-50 is reversible, leading to the slow release of BF . We leveraged this property to reduce the undesirable chain transfer and termination in the cationic polymerization of vinyl ethers. Polymers with higher molecular weights and lower polydispersity were generated compared to those synthesized using BF  ⋅ Et O. The elucidation of the structure-property relationship, as provided by the single-crystal X-ray structures, combined with the high BF uptake capacity and controlled sorption, highlights the molecular understanding of framework-guest interactions in addressing contemporary challenges.
