One-pot route to fine-tuned hypercrosslinked polymer solid acid catalysts

Abstract

Highly sulfonated polymers are promising heterogeneous catalysts due to their excellent chemical and thermal stability, as well as the possibility of employing low-cost synthesis routes. However, their production is time...

Chlorosulfonic acid coated on porous organic polymer as a bifunctional catalyst for the one-pot three-component synthesis of 1,8-naphthyridines

“…3,4,[9][10][11] Today, there is increasing interest in the design and synthesis of heterogeneous supports containing high loads of sulfonic acid groups to increase the turnover number (TON) and turnover frequency (TOF) of the reaction. 12 Despite signicant advances in producing eco-friendly heterogeneous supports (such as cellulose, 13 silica, 14,15 carbon nanotubes, 16 iron aluminate spinel hercynite, 17 graphite carbon nitride, 18 magnetic nanoparticles, 4,5,7,[19][20][21] and polymers 22 ), it is necessary to set certain rules for their applications in terms of their synthesis, recycling, management, and cost.…”

A Robust and Low‐Cost Sulfonated Hypercrosslinked Polymer for Atmospheric Water Harvesting

“…We synthesized a SHCP following our previous report [ 46 ] to reproduce the most highly sulfonated network therein. Briefly, the network was synthesized via the self‐condensation and sulfonation of 4,4′‐bis(chloromethyl)–1,1′‐biphenyl using chlorosulfonic acid as a dual polymerization catalyst and sulfonation agent (synthesis scheme shown in Figure a).…”

“…The chemical and physical properties of SHCP‐10 were characterized extensively and agree well with our previous work (see section 2, Figures S2–S5, and Table S1, Supporting Information). [ 46 ]…”

Hyper crosslinked polymer supported NHC stabilized gold nanoparticles with excellent catalytic performance in flow processes

“…HCP•BIMZ shows only the organic amorphous structures characteristic for HCPs. [25] HCP•NHC-Au(I) contains a small amount of spherical AuNPs due instability of NHC-Au(I) complexes incorporated in the material under ambient conditions. TEM images of HCP•NHC@AuNP display small spherical AuNPs with average size of ~3.5 nm and a narrow size distribution (Figure 2, D).…”
