제목 Covalent Organic Framework with tertiary amine gorups for Efficient SO2 Capture with High Reversibility
초록 We successfully synthesized new series of imide-linked COFs that incorporates DMMA as the modulator via a microwave-assisted reaction. The surface-functionalized channel of imide-linked COF for the interaction with SO2 was achieved through the dimethyl amine functional groups of DMMA. In addition, well-defined large surface areas could afford the channels that can pass SO2 gas through. These imide-based COFs utilizing SO2 and tertiary amine-reversible interactions could be perfectly recovered in a recycling process. Substituted as 10% of the functional group, the molar SO2 sorption capacity was recorded up to 6.30 mmol SO2 g-1 (40 wt%). Furthermore, we found that functionalized PI-COF-m10 was completely reversible for SO2 and highly stable on repeated sorption–desorption cycles. The slightly disturbed crystal structure with 10% tertiary amine functionalization in PI-COF-m10 could accomplish both outstanding SO2 capacity and the high reproducibility.
