Novel magnetic pillar[5]arene polymer as adsorbent for rapid removal of organic pollutants in water or air

Covalently bridged pillararene-based polymers: structures, synthesis, and applications

“…57 Different from grafting pillararenes onto polymers directly, Li and colleagues prepared a magnetic polymer GP-7, where tetrafluoroterephthalonitrile was introduced as a linker to bridge per-hydroxylated pillar [5]arene P28 and magnetic cellulose microparticles (Fe 3 O 4 @SiO 2 @cellulose) covalently. 58 Recently, Qin and coworkers designed and prepared GP-8 by the substitution reaction of the hydrazide groups on pillar [5]arene derivative P27 with terephthaloyl chloride in DMSO-d 6 . 59 The Glaser coupling reaction and photopolymerization reaction are also involved in the construction of GPs.…”

Fabrication of molecularly imprinted resin via controlled polymerization applied in the enrichment of bisphenol A for plastic products

“…As shown in Table S3 and Figure S4, the adsorption profiles of the MIP and NIP are both consistent with the pseudo-second-order kinetic adsorption model, indicating chemisorption processes. A comparison of the results with other relevant reported adsorptions materials [36][37][38][39][40][41], is presented in Table 2. The MIP demonstrates relatively excellent performance, with a saturation adsorption capacity of 387.2 μmol/g and reaching adsorption equilibrium in only 25 min.…”

Cyclodextrin-pillar[n]arene hybridized macrocyclic systems

“…CD-pillar[ n ]arene hybrid macrocyclic system has interesting applications in the removal of organic pollutants from water by taking advantage of both capable host cavities towards diverse pollutants, 79,80 as well as induced chirality and photocatalysis 81,82 due to chiral properties inherited from the chemical architecture of both CD and pillar[ n ]arene.…”
