摘要
报道一种新的、高效的方法合成2,7-二(氮咔唑基)-9,9-二甲基芴(9,9'-(9,9-dimethyl-9H-fluorene-2,7-diyl)bis(9H-carbazole),MFC),并以该物质为聚合单体,以FeCl3为促进剂,在室温下聚合得到聚2,7-二(氮咔唑基)-9,9-二甲基芴(MFC-CMP-1).之后对该聚合物进行性质表征,包括形貌、热稳定性、孔结构等,并进行多种气体(N2、CH4、CO2)的吸附试验.结果表明该材料对CO2表现出良好的吸附性能,其吸附量达到50.4 cm3/g(0.1 MPa和273 K条件下),且吸附选择性良好.这对于设计并合成高效的气体吸附剂、二氧化碳捕集利用和储存相关应用,具有一定的参考价值.
Abstract
9,9'-(9,9-Dimethyl-9H-fluorene-2,7-diyl)bis(9H-carbazole)(MFC)was synthesized with a new and efficient strategy.Then,the porous organic polymer(MFC-CMP-1)with FeCl3 as the accelerator was obtained by self-polymerization at room temperature with MFC as the reaction monomer.The characteristics of MFC-CMP-1(including morphology,thermostability and pore structure)were disclosed and used as an adsorbent to implement the gas(N2,CH4,CO2)capture tests.We were delighted to find that MFC-CMP-1 displayed excellent adsorptive capacity(50.4 cm3/g under 0.1 MPa,273 K)and selectivity for CO2.This research could provide a rational principle for designing,synthesis of efficient adsorbent,and is benefit for the development of carbon capture,utilization and storage.
