In this issue, S. Dai et al. review near-infrared active lead chalcogenide quantum dots. How can they be prepared, modified, and applied in solar cells? The Minireviews deal with advanced materials through photopolymerizationarray-based chemical noses in diagnostics and drug discovery (V. M. Rotello et al.).

In the Communications section, Y.-Q. Lan et al. present adenine components in biomimetic metal–organic frameworks for efficient CO₂ photoconversion (see picture). S. Harder et al. describe nucleophilic aromatic substitution at benzene with strontium hydride and alkyl complexes, and A. Villinger et al. report on the synthesis and structure of cyanidosilicates.
