With methylthio groups flanking the carboxyl groups, the 3,3′,5,5′-tetrakis(methylthio)biphenyl dicarboxylate (TMBPD) linker forms a zirconium(IV) carboxylate porous framework featuring the topology of the UiO-67 prototype, i.e., with a face-centered-cubic array of the Zr₆O₄(OH)₄ clusters. Thioether functionalization proves valuable because the ZrTMBPD crystal is found to be exceptionally stable not only upon long-term exposure to air but also in boiling water and a broad range of pH conditions. The hydrophobicity of the metal–organic framework can also be tuned by simple H₂O₂ oxidation, as illustrated in the water contact-angle measurement of the pristine and H₂O₂-treated ZrTMBPD solid.

单晶UiO-67型多孔网络，对沸水，溶剂损失和氧化稳定

3,3'，5,5'-四（甲硫基）联苯二甲酸二甲酯（TMBPD）接头与甲硫基一起位于羧基的侧面，形成具有UiO-67原型拓扑结构的羧酸锆（IV）多孔骨架。 Zr ₆ O ₄（OH）₄团簇的面心立方阵列。硫醚官能化被证明是有价值的，因为发现ZrTMBPD晶体不仅在长期暴露于空气中而且在沸水和宽范围的pH条件下都非常稳定。金属-有机骨架的疏水性也可以通过简单的H ₂ O ₂氧化来调节，如原始水和H ₂ O ₂的水接触角测量所示。处理的ZrTMBPD固体。
