Continuous flow knitting of a triptycene hypercrosslinked polymer

Chemical Communications, 2019
Hypercrosslinked polymers suitable for carbon capture were produced in continuous flow synthesis using 10% of the time required for typical batch reactions, precluding the need for lengthy reactions to produce microporous polymeric adsorbents.

Selective ·O2- and 1O2-promoted photocatalytic organic transformations by regulating the exciton dynamics through dimensionality control of the PDI-based polymers

Nano Research
Governing the energy transfer (EnT) or electron transfer (ET) excitation pathway to dictate reactive oxygen species (ROS) is crucial for selectivity, yet challenging to achieve with simple molecular designs in highly active systems.

Structural and Compositional Characterization of Fungus‐Derived Pyrolytic Carbon Architectures

Advances in Materials Science and Engineering, Volume 2016, Issue 1, 2016., 2016
Three distinctive pyrolytic carbon structures, derived from three specific tissues of Agaricus bisporus mushroom, were studied and characterized. The three structures discovered within the stalk, cap, and cap skin tissues were found to contain unique microarchitectures, which were preserved upon anoxic carbonization.

Synthesizing Hypercrosslinked Polymers with Deep Eutectic Solvents to Enhance CO2/N2 Selectivity

ChemSusChem, Volume 17, Issue 11, June 10, 2024.
Deep eutectic solvents have been first verified feasible for the synthesis of hypercrosslinked polymers (HCPs) based on Friedel‐Crafts chemistry. Different starting monomers are selected and exhibited significantly improved CO2/N2 selectivity due to narrower pore size distribution in these HCPs, comparing with HCPs synthesized in conventional ...

HYPERCROSSLINKED SORBENTS AND THEIR ADSORPTION PROPERTIES

Bulletin of the Chemical Society of Ethiopia, 2007
Hypercrosslinked sorbents which have excellent adsorption capacities for organic compounds were prepared by cross-linking the polypropylene grafted styrene-divinylbenzene fiber according to the Friedel-Crafts reaction. As crosslinking agents, we have used monochloromethylether and bis-chloromethylated derivatives of benzene or biphenyl.

Adsorptive removal of the pesticide methomyl using hypercrosslinked polymers [PDF]

Journal of Hazardous Materials, 2008
The hypercrosslinked polymers Macronet MN-150 and MN-500 (denoted as MN-150 and MN-500) were investigated to remove the pesticide methomyl from aqueous solutions via adsorption. Furthermore, the effect of humid acid (used as background organic compound) on the adsorption capacity of methomyl for MN-150 was examined.

Hypercrosslinked Phenolic Polymers with Well‐Developed Mesoporous Frameworks

Angewandte Chemie, 2015
AbstractA soft chemistry synthetic strategy based on a Friedel–Crafts alkylation reaction is developed for the textural engineering of phenolic resin (PR) with a robust mesoporous framework to avoid serious framework shrinkage and maximize retention of organic functional moieties. By taking advantage of the structural benefits of molecular bridges, the
