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

Popis výsledku v původním jazyce

PIM-Trip-TB provides highly impressive gas permeation data for a number of commercially relevant gas pairs including O2 / N2, H2 /N2 and CO2 /CH4 in terms of permeability, selectivity and position relative to the 2008 Robeson upper bound. This performance is based on exceptional diffusivity selectivity of gas transport. The lack of methyl groups in PIM-Trip-TB may enhance performance as compared to PIM-EA-TB, within which methyl rotary motion may reduce diffusivity selectivity. Indeed, as PIM-Trip-TB is a ladder polymer that is composed of only benzene rings fused together by rigid bridged bicyclic units and contains no groups that can act as rotors, its performance as a molecular sieve is likely to be approaching the optimum achievable for gas separation for a solution processable polymer. Any further improvement in fundamental gas permeability data may require the additional enhancement of solubility selectivity for one gas over another.
