In this issue, F. Würthner et al. review the history of J-aggregates. What supramolecular construction principles, optical properties, and perspectives for applications are relevant today? The selective oxidation of C–H bonds is the subject of a Minireview by T. Newhouse and P. Baran. The Highlights deal with ligands that store and release electrons during catalysis (B. de Bruin et al.) and synthetic molecular bipeds (E. M Pérez). In an Editorial, A. Kreimeyer (BASF, member of Angewandte’s Editorial Board) comments on chemistry as an innovation driver.
In the Communications section, J. R. Nitschke et al. report on a self-assembled cubic cage that encapsulates aromatic molecules as large as fullerenes. K. Maruoka et al. describe an umpolung strategy that allowed them to carry out an asymmetric 1,3-dipolar cycloaddition of C,N-cyclic azomethine imines. T. Ma et al. present low-cost molybdenum and tungsten carbide counter electrodes for dye-sensitized solar cells (see picture).
