This week, B. M. Trost and L. Czabaniuk review the structure and reactivity of late transition metal η³-benzyl complexes. Can such species be catalytic intermediates? In a Minireview, S. Ahmad et al. discuss the game-changing role of perovskites in photovoltaics. The Highlight deals with the modulation of the coordination sphere of f-element complexes by fluorocarbons (S. Alvarez and B. Menjón). In an Editorial, A. Heller explains how publically funded applied research should be managed.

In the Communications section, A. Centrone et al. assess nanoscale chemical heterogeneity in mixed-ligand metal–organic frameworks (see picture). Y. Watanabe et al. investigate the inhibition of heme uptake in P. aeruginisa by its hemophore bound to synthetic metal complexes. S. Ghosh et al. reveal the reactivity of diruthenium and dirhodium analogues of pentaborane(9). Q. Xu et al. report on the combinatorial design of lipid-like nanoparticles for intracellular delivery of cytotoxic proteins. P. Melchiorre et al. present asymmetric vinylogous Diels–Alder reactions that are catalyzed by a chiral phosphoric acid.
