The Cover Feature shows a mesoporous ionic crystal composed of a Keggin‐type polyoxometalate and a macrocation with Cr(III), catalyzing fructose dehydration to 5‐hydroxymethylfurfural (HMF), which is an important bio‐based chemical, without any apparent by‐products at mild conditions. In their Communication, Sayaka Uchida and co‐workers synthesize three ionic crystals with analogous building blocks but different pore sizes, and showed that the catalytic activities were basically dependent on the porosity. The results show the structure‐function relationships in heterogeneous catalysis of porous ionic crystals. More information can be found in the Communication by Takumi Yamada et al. on page 3745 in Issue 16, 2019 (DOI: 10.1002/cctc.201900614).
