Abstract:

A novel microporous organic polymer TP-MOP containing Troger's base (TB) has been constructed by a simple one-pot reaction through the condensation of 1,3,6,8-tetrakis(4-aminophenyl)pyrene (TP) with dimethoxy-methane (DMM) under ambient condition. The N-2 adsorption isotherm of TP-MOP at 77 K indicates typical type-1 sorption behavior with a Brunauer-Emmett-Teller (BET) surface area of 1066 m(2)g(-1). Fascinatingly, it exhibits high carbon dioxide adsorption capacity up to 254.6 cm(3)g(-1) at 1 bar, 273 K. Moreover, probably due to the presence of Troger's base moiety, the isosteric heat (Q(st)) 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 LAST (the ideal adsorbed solution theory) selectivities of TP-MOP are 93-65.8 for a CO2/N-2 (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.
