Indium(iii)–dicarboxylic microporous frameworks with high adsorption selectivity for CO2 over N2

Abstract

Two microporous metal-organic frameworks formulated as H2In3O(OH)3(1,3-bdc)3 (1) and HIn(1,4-bdc)2 (2) (bdc = benzenedicarboxylic) were designed and synthesized. Compound 2 shows a high adsorption selectivity for CO2 over N2 as well as a high stability.

Auxiliary ligand-assisted two novel one-dimensional indium coordination polymers: Synthesis, crystal structures and photoluminescence characterization effected by solvent and temperature

“…1b) between those found in indium CPs [31], except the distance of In-O6 (2.643(6) Å). This longest distance of In-O could help to reduce the steric hindrance.…”

“…The emission spectrum of In2 solid-state sample at 298 K is centered at 400 nm, which is similar to that of the free 1,4-H 2 bda ligand (λ em = 414 nm) with 14 nm blue shift. It may be due to that the 1D zigzag-like chain mode can induce a slight increase of the HOMO-LUMO energy gap of the 1,4-bda 2− ligand in In2 [31]. In1 and In2 produce blue emission with the Commission Internacionale d'Eclairage (CIE) coordinates 0.20, 0.13 and 0.20, 0.06, respectively.…”

Enhanced Sieving of C2‐Hydrocarbon from Methane by Fluoro‐Functionalization of In‐MOF with Robust Stability

“…Both MOFs exhibited typically reversible type‐I isotherms for microporous networks. The Brunauer‐Emmett Teller (BET) surface areas were 224 and 217 m 2 g −1 and the sorption amounts are 150 and 76.7 cm 3 ⋅ g −1 for QMOF‐2 [21] and QMOF‐2F , respectively. Comparatively, QMOF‐2F showed a slightly less surface area and sorption amount than QMOF‐2F , as it was expected from the presence of fluorine substituents.…”

“…Before the adsorption studies on light hydrocarbons, N 2 sorption isotherm at 77 K were recorded (Ref. 21 and Figure S8a). Both MOFs exhibited typically reversible type-I isotherms for microporous networks.…”

Synthesis, Structure, and Selected Properties of Aluminum-, Gallium-, and Indium-Based Metal-Organic Frameworks

“…The topological representation of both of these nodes can be described as trigonal prismatic. In [In 3 (OH 2 )(OH) 3 (m-BDC) 3 ] [19], these inorganic units are linked by six isophthalate ions to form a 3D framework.…”
