The Cover Feature illustrates the relation between the Hammett parameter (σ) of substituents and the activity (TOF) of rhodium catalysts heterogenized inside molecularly defined porous structures, as shown in the background. In their Communication, F. M. Wisser et al. demonstrate how, like in a famous word game, porous solids such as metal‐organic frameworks and microporous polymers can be rationally assembled from building blocks to reach the desired Hammett constant. The unique linear correlation between Hammett constant and activity for MOF‐, polymer‐supported and homogeneous catalysts highlights the crucial impact of the local electronic environment surrounding the active site over the long‐range porous support structure. MOF and microporous polymers used to heterogenize molecular catalysts further reduce the gap between homogeneous and heterogeneous catalysis. More information can be found in the Communication by F. M. Wisser et al. on page 1778 in Issue 8, 2018 (DOI: 10.1002/cctc.201701836).
