Covalent triazine-based framework directly synthesized from aromatic amides |
| 초록 |
Since the birth of covalent organic frameworks (COFs), extensive efforts have been dedicated to synthesis of crystalline materials for practical applications. For the first-time, phosphorus pentoxide (P2O5) catalyzed condensation reaction of aromatic amide to form triazine ring was applied on terephthalamide to construct triazine-based framework. This unique approach yields, highly crystalline covalent triazine frameworks (pCTF-1) with high specific surface area (2039.1 m2 g−1). At low pressure, pCTF-1 shows high CO2 (21.9 wt% at 273 K) and H2 (1.75 wt% at 77 K) uptake capacities. The direct formation of triazine ring was also confirmed by model reaction with P2O5-catalyzed condensation reaction of benzamide and aromatic nitrile to form 1,3,5-triphenyl-2,4,6-triazine (TTA) in high yield. |
