A nanoporous organic polymer constructed from a 1,3,5-triazine derivative via ethynyl cyclotrimerization reaction: Synthesis and carbon dioxide capture
Abstract
Ethynyl cyclotrimerization reaction of 2,4,6-tris(4-ethynylphenyl)-1,3,5-triazine (2) results in a nanoporous organic polymer. The structure of the resulting polymer, TNOP is characterized by FT-TR, solid-state 13C NMR spectroscopy and elemental analysis. TNOP shows high thermal stability and is highly porous with Brunauer-Emmett-Teller specific surface area (SBET) of 755 m2 g–1, total pore volume of 0.43 cm3 g–1 and relatively narrow pore size distribution. For applications, TNOP possesses a moderate carbon dioxide uptake of 1.02 mmol g–1 (4.49 wt%) at 298 K and at 1.03 bar, suggesting its potential application in storing and capturing carbon dioxide.
