Two-dimensional covalent organic frameworks (2D-COFs) are excellent candidates for photocatalytic organic transformations due to their periodic columnar π-arrays and ordered nanochannels. Here, we present a novel 2D-COF that features permanent porosity with high surface area and large pore volume, and exhibits a high crystallinity and an excellent stability. Indeed, the new 2D-COF was found to be a
二维共价有机骨架(2D-COF)由于其周期性的柱状π阵列和有序的纳米通道,是光催化有机转化的极佳候选者。在这里,我们提出了一种新颖的2D-COF,其特征是具有高表面积和大孔体积的永久孔隙率,并具有高结晶度和出色的稳定性。确实,新的2D-COF被发现是一种高效的,无金属的,可回收的多相光催化剂,用于在可见光照射下使用O 2作为绿色氧气源的氧化CH-H功能化。
