The cover feature shows a novel synthetic route for improving the formation of metal–organic frameworks (MOFs). This route is triggered by hydrogen peroxide (H2O2) to promote the formation of terephthalate‐based MOFs of MIL‐53 and MIL‐68 types. Following the standard synthetic route, chains of terephthalate bridges form first, thus delaying the synthesis of the MOF. However, the presence of H2O2 promotes the early formation of μ‐hydroxo bridges and then terephthalate ligands link aluminum‐containing species to give rise to the μ‐carboxylate bridges between metallic atoms, leading to a faster growth and high yield of the final MOF. More details are given in the Communication by V. Sebastian, J. Coronas, and co‐workers (DOI: 10.1002/cplu.201900492).

过氧化氢对对苯二甲酸基金属有机骨架合成的影响
封面功能显示了一种新颖的合成途径，可改善金属有机骨架（MOF）的形成。该途径由过氧化氢（H 2 O 2）触发，以促进基于MIL-53和MIL-68型对苯二甲酸酯的MOF的形成。按照标准的合成路线，首先形成对苯二甲酸酯桥链，从而延迟了MOF的合成。但是，H 2 O 2的存在促进μ-羟基桥的早期形成，然后对苯二甲酸酯配体将含铝物质连接起来，从而在金属原子之间形成μ-羧酸根桥，从而导致最终MOF的更快生长和高产率。V.Sebastian，J.Coronas及其同事的来信（DOI：10.1002 / cplu.201900492）中提供了更多详细信息。
