| Popis: | The synthesis, porosity and the capability for carbon dioxide gas-capture of functionalized thiophene- pyridine microporous imine-linked polymer synthesized via the Schiff base condensation reaction between (1,3,5-triformyl thienyl benzene) and 2,6-diaminopyridine is described. The structural formation of the polymer was successfully confirmed via 13C NMR (CP-MAS) and IR spectroscopy, and elemental analysis. The polymer has the good thermal stability up to 380°C, a non-defined aggregated particles morphology and amorphous nature. From the argon sorption isotherm at 87 K, the polymer revealed a moderate Brunauer–Emmett–Teller surface area (372 m2/g) and micro-size pores (~5 A). The CO2 uptake was studied at 273 and 298 K to evaluate the polymer tendency for capturing CO2 from the surrounding atmosphere. At 298 K, the polymer has shown a reversible adsorption-desorption isotherm with significant uptake (11.4 wt %) at 1.0 atm. The binding energy of CO2 at zero gas coverage is 24 kJ/mol and decreased upon loading. |
