Triptycene Induced Enhancement of Membrane Gas Selectivity for Microporous Tröger's Base Polymers

Triptycene-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, ...

Palladium nanoparticles supported on a triptycene-based microporous polymer: highly active catalysts for CO oxidation.

Pd nanoparticles were well dispersed on a new triptycene-based microporous polymer support by the gas bubbling-assisted membrane reduction (GBMR) method. The stability of Pd nanoparticles is improved by the porous support, and the materials show excellent performance for CO oxidation.

Central composite experimental design applied to fabrication of LLDPE microporous membrane via thermally induced phase separation (TIPS) method

Photo-oxidative enhancement of polymeric molecular sieve membranes.

High-performance membranes are attractive for molecular-level separations in industrial-scale chemical, energy and environmental processes. The next-generation membranes for these processes are based on molecular sieving materials to simultaneously achieve high throughput and selectivity. Membranes made from polymeric molecular sieves such as polymers of intrinsic microporosity (pore size<2 nm)...

Main-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...
