In this work, we report a new polyoxovanadate–resorcin[4]arene-based metal–organic framework (PMOF), [Co₂L_0.5V₄O₁₂]·3DMF·5H₂O (1), assembled with a newly functionalized wheel-like resorcin[4]arene ligand (L). 1 features an elegant porous motif and represents a rare example of PMOFs composed of both a resorcin[4]arene ligand and polyoxovanadate. Remarkably, 1 shows open V sites in the channel, which makes 1 an efficient heterogeneous Lewis acid catalyst for the cycloaddition of carbon dioxide to epoxides with high conversion and selectivity. Strikingly, 1 also exhibits high catalytic activity for the heterogeneous oxidative desulfurization of sulfides. Particularly, the heterogeneous catalyst 1 can be easily separated and reused with good catalytic activity.

一种基于聚氧钒酸盐-间苯二酚[4]芳烃的多孔金属-有机骨架，作为高效的多功能催化剂，可将CO ₂与环氧化物加成并硫化物选择性氧化

在这项工作中，我们报告了一种新的聚氧钒酸盐-间苯二酚[4]芳烃基金属-有机骨架（PMOF），[Co ₂ L _0.5 V ₄ O ₁₂ ]·3DMF·5H ₂ O（1），该结构与新功能化的组装在一起轮状间苯二酚[4]芳烃配体（L）。1具有优雅的多孔基序，并代表了由间苯二酚[4]芳烃配体和聚氧钒酸盐组成的PMOF的罕见实例。显着地，1在通道中显示出开放的V位，这使1成为高效的异质路易斯酸催化剂，可高转化率和选择性地将二氧化碳环加成环氧化物。惊人地，1对硫化物的非均相氧化脱硫也具有很高的催化活性。特别地，多相催化剂1可以容易地分离并以良好的催化活性再利用。
