We successfully prepared two different kinds of hyper-crosslinked porous organic polymers (CPOPs) based on tetraphenylanthraquinone units by a reaction of 9,10-bis(diphenylmethylene)- 9,10-dihydroanthracene (An-4Ph) as the building unit with formaldehyde dimethyl acetal and 2,4,6-trichloro-1,3,5-triazine as two external crosslinkers by using a simple and friendly one-step Friedel−Crafts polymerization in the presence anhydrous FeCl3 as a catalyst to afford An-CPOP-1 and An-CPOP-2 as a black solid with high yield, respectively. Fourier-transform infrared (FTIR) and NMR spectroscopy were confirmed the chemical structures of the synthesized monomer and the corresponding polymers. Both An-CPOP-1 and An-CPOP-2 possess amorphous character, outstanding thermal stability, and high BET surface area (up to 1000 m2/g) with microporosity and mesoporosity architectures based on XRD, TGA analyses and N2 adsorption/desorption measurements. Interestingly, TEM and SEM images revealed that An-CPOP-1 had regular tubular nanotubes structure without using template or surfactant or carbonization at the elevated temperature. The as-prepared An-CPOP-2 exhibited a high specific capacitance of 98.4 F g−1 at a current density of 0.5 A g−1 and excellent cycling stability (95.3% capacitance retention over 2000 cycles), which could be used as good material for energy storage application.

基于四苯基蒽醌的超交联多孔有机聚合物,可吸收CO 2和高性能超级电容器

我们成功地通过以9,10-双(二苯基亚甲基)-9,10-二氢蒽(An-4Ph)作为建筑单元与甲醛二甲基的反应,成功地制备了基于四苯基蒽醌单元的两种不同类型的超交联多孔有机聚合物(CPOP)。乙缩醛和2,4,6-三氯-1,3,5-三嗪作为两个外部交联剂,通过在无水FeCl 3作为催化剂存在下使用简单友好的一步式Friedel-Crafts聚合反应得到An-CPOP-1和An-CPOP-2分别为黑色固体,产率高。傅里叶变换红外(FTIR)和NMR光谱证实了合成单体和相应聚合物的化学结构。An-CPOP-1和An-CPOP-2均具有非晶态特性,出色的热稳定性和高BET表面积(高达1000 m2 / g)具有基于XRD,TGA分析和N 2吸附/解吸测量的微孔和中孔结构。有趣的是,TEM和SEM图像显示An-CPOP-1具有规则的管状纳米管结构,而无需使用模板或表面活性剂或在高温下碳化。所制备的An-CPOP-2在电流密度为0.5 A g -1时表现出98.4 F g -1的高比电容,并具有出色的循环稳定性(在2000次循环中保持95.3%的电容),可以很好地使用。储能材料。
