Two novel thorium-based organic frameworks (Th-IHEP-5 and Th-IHEP-6) were assembled from a hexanuclear thorium cluster, porphyrin derivative ligand and linear carboxylic acid ligands via a mixed-ligand strategy. As a stable heterogeneous catalyst, Th-IHEP-5 exhibited high photocatalytic activity for the oxidation of 2-chloroethyl ethyl sulfide (CEES) and the fixation of CO2. The good catalytic effect is attributed to the large conjugated system of porphyrin and the photosensitizer enhancing effects of bipyridine.

混合配体策略可调节基于or的MOF。

通过混合配体策略，从六核th簇，卟啉衍生物配体和线性羧酸配体组装了两个基于th的新型有机骨架（Th-IHEP-5和Th-IHEP-6）。作为稳定的非均相催化剂，Th-IHEP-5对2-氯乙基乙基硫醚（CEES）的氧化和CO2的固定具有很高的光催化活性。良好的催化作用归因于卟啉的大共轭体系和联吡啶的光敏剂增强作用。
