Triptycene Induced Enhancement of Membrane Gas Selectivity for Microporous Tröger's Base Polymers
A highly gas permeable polymer with exceptional size selectivity is prepared by fusing triptycene units together via a poly-merization reaction involving Tröger's base formation. The extreme rigidity of this polymer of intrinsic microporosity (PIM-Trip-TB) facilitates gas permeability data that lie well above the benchmark 2008 Robeson upper bounds for the important O2 /N2 and H2 /N2 gas pairs.
متن کاملTriptycene-Based Microporous Polymer Incorporating Thioamide Functionality: Preparation and Gas Storage Properties
Triptycene-based micorporous polymer was functionalized with thioamide moieties via post-polymerization using phosphorus pentasulfide as a thionating agent in the presence of sodium sulfite. Gas adsorption experiments indicate that the modification leads to a reduction in the BET surface area of the polymer, from 1640 m g for the parent TMP to 207 m g on 74% conversion of nitrile to thioamide, ...
متن کاملHigh CO2 uptake and selectivity by triptycene-derived benzimidazole-linked polymers.
Successful incorporation of triptycene into benzimidazole-linked polymers leads to the highest CO(2) uptake (5.12 mmol g(-1), 273 K and 1 bar) by porous organic polymers and results in high CO(2)/N(2) (63) and CO(2)/CH(4) (8.4) selectivities.

The absorption of hard spheres into narrow pores is examined in the framework of RosenfeldÏs ““ fundamental measure ÏÏ formulation of density functional theory (DFT) for inhomogeneous Ñuids. The inÑuence of the dimensionality of the conÐning geometry is assessed by considering the cases of a spherical cavity, an inÐnite cylindrical channel and an inÐnite slit. The pores are assumed to be in che...
متن کاملMain-chain organometallic microporous polymers based on triptycene: synthesis and catalytic application in the Suzuki-Miyaura coupling reaction.
Significance: A triptycene-based NHC-Pd mainchain organometallic microporous polymer (MOMP-1) was prepared from 2,6,14-triiodotriptycene according to Scheme 1. MOMP-1 catalyzed the Suzuki–Miyaura coupling of aryl halides with phenylboronic acid in water to give the corresponding biaryls in 88–97% yield (Scheme 2, 9 examples). Comment: The characterization of MOMP-1 was performed by NMR, SEM, TE...
