In this issue, D. Ma et al. review copper-based reactions for C–N, C–O, C–S, and C–C bond formation. How can they be useful in couplings of (hetero)aryl halides with various nucleophiles? In a Minireview, K. Heinze quests for mononuclear gold(II) and its potential role in photocatalysis and drug action. The Highlight deals with chiral imprinting in the gas phase (D. W. Pratt and B. H. Pate).

In the Communications section, C. Park et al. introduce the facile supramolecular processing of carbon nanotubes and polymers for electromechanical sensors (see picture). D.-G. Cho et al. present a synthesis of a phlorin from a meso-fused anthriporphyrin by a Diels–Alder strategy. E. Cariati et al. found cyclic triimidazole derivatives to be intriguing molecules with multiple emissions and ultralong phosphorescence at room temperature.
