photocurrent, compared to those of the irregular solid CMP counterpart. When serving as a metal-free photocatalyst for an undocumented visible-light-driven thiocyanation of anilines, CMP-1 exhibits excellent photocatalytic performance, with single chemoselectivity and high yields for the conversion of 25 types of anilines at ambient conditions. This study fills in the gap of the tubular morphological engineering
共轭微孔聚合物(CMP)是功能材料的一种重要类型。在这一领域,形态工程仍然是一个重大挑战。在这里,我们报告通过无模板协议基于卟啉的CMP管(CMP-1)的合成。机理研究表明,CMP管是由带状结构的滚动和闭合形成的。与不规则固体CMP对应物相比,这些管具有495 m 2 / g的高比表面积,并具有改进的光学特性,包括在可见光区域的吸收更宽,三重态寿命更长,光电流更稳定。 。当用作无证的可见光驱动的苯胺的硫氰化的无金属光催化剂时,CMP-1具有优异的光催化性能,具有单一的化学选择性和高收率,可在环境条件下转化25种苯胺。这项研究填补了CMP的管状形态工程学的空白,并拓宽了其潜在应用范围。
