Lithiated Porous Aromatic Frameworks with Exceptional Gas Storage Capacity

Abstract

Steigerung durch Reduktion: Die Lithiierung des porösen aromatischen Gerüsts PAF‐1 (blaue Struktur) führt zu einem reduzierten Gerüst mit höherer Gasspeicherkapazität (um 22, 71 und 320 % für H2, CH4 bzw. CO2 im Vergleich zu PAF‐1). Das reduzierte Gerüst wurde spektroskopisch untersucht, und seine potenzielle Wasserstoffspeicherkapazität wurde berechnet.

Ending Aging in Super Glassy Polymer Membranes

“…[22] Brunauer-Emmett-Teller (BET) surface areas in PAFs are as high as 5200 m 2 g À1 , which with functionalization can lead to ultrahigh affinities for adsorption of carbon dioxide and other gases. [23] The regular nanopores of around 1.2 nm diameter ( Figure S9 in the Supporting Information) are attractive for the intercalation of polyacetylene side-chain or bulky chemical moieties in PIMs, thereby freezing the as-cast lower-density polymer structure in place and tuning the aging process. This mechanism is distinct from the enhanced permeability effect of non-porous nanoparticle [24] and porous nanoparticle [25] additions to super glassy polymers that prop open the polymer chains at the nanoparticle/polymer boundary but do not prevent aging.…”

Porous aromatic framework (PAF-1) as hyperstable platform for enantioselective organocatalysis

“…So far PAF-1 and functionalized PAF-1 have been widely used for adsorption [43][44][45][46][47][48][49][50][51][52][53][54][55][56], separation [57,58], heterogeneous catalysis [59], detection [60] and other diverse applications [61][62][63][64]. On the one hand, PAF-1 has high level of porosity and extraordinary stability to thermal treatments and almost all of the solvents.…”

Triptycene-Based Microporous Polymer Incorporating Thioamide Functionality: Preparation and Gas Storage Properties

“…A notable achievement in porous materials research is the development of micorporous organic polymers, which exhibit unique properties of large specific surface area, narrow pore size distribution, high chemical stability, low skeleton density, and the ability to be fine-tuned in their properties at the molecular level, allowing facile construction of porous materials with desired functionalities by appropriate choice of building block [3][4][5]. Such organic porous structure has flexibility of varying in designing organic functional monomers and pendant functional moieties, and can effectively combine the organic synthetic methodologies with processability of polymer, thus providing a unique opportunity for rational design and development of versatile microporous polymers for targeted applications.…”
