Abstract:

A novel microporous organic polymer TP-MOP containing Tröger's base (TB) has been constructed by a simple one-pot reaction through the condensation of 1,3,6,8tetrakis(4aminophenyl)pyrene (TP) with dimethoxymethane (DMM) under ambient condition. The N2 adsorption isotherm of TP-MOP at 77 K indicates typical type-I sorption behavior with a Brunauer–Emmett–Teller (BET) surface area of 1066 m2 g−1. Fascinatingly, it exhibits high carbon dioxide adsorption capacity up to 254.6 cm3 g−1 at 1 bar, 273 K. Moreover, probably due to the presence of Tröger's base moiety, the isosteric heat (Qst) of CO2 adsorption for TP-MOP can reach as high as 40.4 kJ mol−1. This consequently boosts the CO2 uptake and/or CO2 selectivity over nitrogen and methane. Impressively, at 278 K, the predicted IAST (the ideal adsorbed solution theory) selectivities of TP-MOP are 93-65.8 for a CO2/N2 (15/85 v/v) gas mixture and 8.3–6.7 for a CO2/CH4 (50/50 v/v) gas mixture at pressures varying from 0 to 1 atm, respectively. © 2019 Elsevier Inc.
