Large-Scale Synthesis of Covalent Organic Frameworks: Challenges and Opportunities

Membranes, Journal Year: 2023, Volume and Issue: 13(8), P. 696 - 696

Published: July 27, 2023

Connecting organic building blocks by covalent bonds to design porous crystalline networks has led frameworks (COFs), consequently transferring the flexibility of dynamic linkages from discrete architectures extended structures. By virtue library and diversity topologies, COFs have emerged as a novel field materials that propose platform for tailor-made complex structural design. Progress over past two decades in design, synthesis, functional exploration diverse applications successively established these chemistry. The large-scale synthesis with uniform structures properties is profound importance commercialization industrial applications; however, this its infancy at present. An innovative designing synthetic approaches paved ways address future hurdles. This review article highlights fundamental COFs, including principles, coupling reactions, diversity, strategies, characterization, growth mechanism, activation aspects COFs. Finally, major challenges trends COF fabrication are outlined.

Enhanced Catalytic Activity for Levulinic Acid Esterification Using Covalent Organic Framework Heterogenized Heteropolyacids

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(10), P. 4286 - 4299

Published: Feb. 26, 2024

Alkyl levulinates act as crucial additives in gasoline and biodiesel are largely produced through esterification of levulinic acid (LA) with alcohols using homogeneous acids suffering from equipment corrosion low reusability issues. Here, this work, a phosphotungstic (HPW) catalyst was heterogenized via incorporation on 2D imine-based covalent organic framework material (LZU1) to obtain heterogeneous HPW-LZU1 catalyst. The synthesis process comprehensively monitored 1H NMR, solid 13C MAS ATR-FTIR, etc. When the HPW/LZU1 mass ratio 8.6, exhibited an excellent catalytic activity, >90% conversion LA 100% selectivity alkyl obtained, comparable HPW Catalytic performance without obvious decrease after five cycles demonstrated stability as-prepared In situ FTIR study shows that dominantly adsorbed Brönsted sites, while methanol Lewis sites.
