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 m2/g and high activity and selectivity for photo-driven 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.
