In a groundbreaking work of discovering dibenzo-18-crown-6 (DB18C6) by Pederson in 1967, DB18C6 has been used for many applications such as a receptor in supramolecular chemistry, host in host-guest chemistry, and copolymer in gas-separation applications. In this work, we will show Tröger’s base- based dibenzo crown ether polymer used for gas- separation applications. Tröger’s base- based dibenzo crown ether polymer was synthesized from trans diamino DB18C6. The synthesized polymer was characterized by NMR, GPC, MALDI. The membrane was cast and gas separation data were obtained for different gases i.e H2, CO2, CH4, O2. In this work, improved gas permeability selectivity was developed for CO2/N2; H2/N2; CH4/N2. Synthetic route to obtain Tröger’s base- based dibenzo crown ether and its selectivity of H2 and CO2 versus other gases data will be presented.
