      However, conventional MOFs like ZIF-8, UiO-66-NH2 and MIL-100(Fe)—widely studied for QNs' adsorption26–29—often suffer from limited micropores (<10 Å) and/or narrow pore apertures due to short ligand constraints,30 hindering mass transport of bulky pharmaceuticals.

      CUH 和 CUF 的孔体积和比表面积通过 N₂吸附-脱附等温线获得。如图 2c 所示，CUH 和 CUF 的 N₂吸附-脱附等温线呈现典型的 I 型吸附-脱附等温线，在 0–0.2P/P0 范围内呈现急剧上升趋势，根据 IUPAC 分类[24]表明存在微孔结构，而 CUF 显示出更高的 N₂吸附容量。CUH 和 CUF 的比表面积和孔径数据展示于表 S3 和图 2c 中。与 CUH 相比，比表面积从 933.20 m²/g 增加至 1002.78 m²/g，平均孔径从 1.06 nm 增大至 1.09 nm，表明具有不对称结构的有机连接体能够扩大与反应物的接触面积并暴露更多活性位点。这些改进的特性有助于增强催化剂的吸附性能，促进 PMS 活化产生活性氧物种。

      在金属有机框架（MOF）中引入结构不规则性（即缺陷和电子不对称性），有助于为 MOF 材料带来额外的孔隙结构和丰富的活性位点，从而提升其选择性、渗透性和催化反应活性[9]。调制剂诱导策略（如甲酸、胺类及第二金属的引入）被视为在 MOF 材料上构建短程无序缺陷的常用方法，其中调制剂参与无机簇或次级结构单元的构建[10, 11]。
