1Crystalline porous ionic salts assembled from polyoxometalates and cationic capsule for the selective photocatalytic aerobic oxidation of aromatic alcohols to aldehydes显示文摘Crystalline porous ionic salts(CPISs) represent a new type of porous materials constructed by electrostatic interaction, however, synthesis of CPISs bearing pre-designed functionality while exhibiting permanent porosity is still challenging. Herein we report the facile synthesis of a series of CPISs 1-3 built from photocatalytic-active polyoxometalate(POM) clusters and cationic Zr-based capsules, which showed open porous frameworks with BET surface area up to 33 m^(2)/g and high activity and selectivity for photodriven aerobic oxidation of alcohols to aldehydes. Compared with the pristine POM cluster {W10}, 1 can promote the reaction in much higher efficiency due to the concerted catalysis of preinstalled {W10} and Zr-based capsule together with open channels. This work highlights the advantage of CPISs as porous heterogeneous catalysts in organic transformation, and may shed light on the rational design of more delicate CPISs-derived functional materials.Qianxia Gu Xiao-Li Zhao Min Meng Zhiyu Shao Qi Zheng Weimin Xuan 2023Chinese Chemical Letters2023,34,4:0
