Crystalline materials with multi-catalytic applications are of great value to both fundamental research and practical applications. The platform of metal–organic frameworks (MOFs) is utilized to fabricate a microporous versatile catalyst with high stability. Self-assembly of a flexible ligand, 4-(4-carboxybenzylamino)benzoic acid (H₂CBBA), with Co(II) resulted in a 3D framework, CBBA-Co, with Co₃O clusters exposed in the zigzag channels. Upon in situ activation, CBBA-Co exhibited multiple heterogeneous catalytic activities. Theoretical calculations were carried out to give insights into the catalytic process. In addition, CBBA-Co also showed promising potential in optical sensing by virtue of its catalytic activity. The luminol chemiluminescence was greatly enhanced by CBBA-Co, and linear determination of the concentration of H₂O₂ in the range of 0–30% was established. The successful implementation of CBBA-Co indicates the feasibility and promising future of employing MOFs as an efficient platform for the fabrication and study of multifunctional catalysts, both experimentally and theoretically.

多功能的基于Co的金属-有机框架：异相催化，化学发光传感和湿度依赖性溶剂致变色†

具有多种催化作用的结晶材料对于基础研究和实际应用都具有巨大的价值。金属-有机骨架（MOFs）平台被用来制造具有高稳定性的微孔多用途催化剂。柔性配体4-（4-羧基苄基氨基）苯甲酸（H ₂ CBBA）与Co（II）的自组装产生了3D框架CBBA-Co，其中Co ₃ O簇暴露在锯齿形通道中。在原位在活化过程中，CBBA-Co表现出多种非均相催化活性。进行了理论计算，以深入了解催化过程。此外，CBBA-Co还具有催化活性，在光学传感方面也显示出广阔的前景。CBBA-Co大大增强了鲁米诺的化学发光，建立了线性测定H ₂ O ₂浓度在0-30％范围内的方法。CBBA-Co的成功实施表明，在实验和理论上，将MOF用作制备和研究多功能催化剂的有效平台具有可行性和前途。
