摘要

同时追求结构均匀性/结晶性和功能复杂性是功能材料工程的一个长期目标。通常情况下,增强一种属性的努力可能会损害另一种属性。在本文中,我们报告了一种将催化中心整合到调制剂中的精心设计的策略,它实现了双功能金属有机框架(MOF)Zr-TBAPy-TSA(TBAPy = 1,3,6,8-四(对苯甲酸)芘;TSA = 邻硫代水杨酸)的一锅合成。TSA 既是金属有机框架 (MOF) 制备的调制剂,也是催化中心。Zr-TBAPy-TSA 的独特之处在于其高度均匀的结晶结构,单晶 X 射线衍射等详细表征证明了这一点。此外,同时包含光敏剂和硫醇活性中心的 Zr-TBAPy-TSA 在活化元素-H 键(元素包括 C、B、Si 和 P)方面表现出卓越的催化性能。由于其结构缺陷较少,因此可获得高达 14,200 的超高周转次数和良好的催化剂可回收性。

Modulator engineering of bifunctional metal-organic framework for synergistic catalysis

Modulator engineering of bifunctional metal-organic framework for synergistic catalysis
Pursuing both structural uniformity/crystallinity and functional complexity is a long-term goal in functional materials engineering. Often, efforts to enhance one attribute may compromise the other. Herein, we report an elaborate strategy of integrating a catalytic center into a modulator, which enables the one-pot synthesis of a bifunctional metal-organic framework (MOF), Zr-TBAPy-TSA (TBAPy = 1,3,6,8-tetrakis(p-benzoic acid)pyrene; TSA = o-thiosalicylic acid). TSA serves as both a modulator for metal-organic framework (MOF) preparation and a catalytic center. Zr-TBAPy-TSA is distinguished by its highly uniform and crystalline structure, as evidenced by detailed characterizations including single-crystal X-ray diffraction. Additionally, Zr-TBAPy-TSA incorporating both photosensitizer and thiol active centers showcases superior catalytic performance in the activation of element–H bonds (elements include C, B, Si, and P). Due to its less defective structure, extra high turnover numbers of up to 14,200 and good catalyst recyclability are obtained.
