In this issue, B. L. Feringa et al. review the self-assembly of photoresponsive molecular amphiphiles in aqueous media, and W. Leitner et al. summarize research on transition metal complexes as catalysts for the electroconversion of CO₂ from an organometallic perspective. The Minireviews deal with synthetic DNA for cell-surface engineering (P. Shi, Y. Wang) and lead-free double perovskite Cs₂AgInCl₆ (Z. Xia et al.).

N. V. Muravyev wonders about variations of computed detonation performance in a Correspondence and J. M. Shreeve et al. reply, citing the range of computational methods used. In an Essay, J. S. Leigh et al. address equality, diversity, and inclusion issues within supramolecular chemistry. C. Thilgen, H. Wennemers, and T. Carell highlight the scientific legacy and life of François Diederich in an Obituary.

In the original research section, S. Kitagawa et al. describe the host–guest interaction modulation in porous coordination polymers for inverse selective CO₂/C₂H₂ separation (see picture). Z. Huang et al. developed an amine–borane system that dehydrogenates and regenerates at room temperature. F. Ye et al. found dynamically re-organized collagen fiber bundles to transmit mechanical signals and induce cell migration and self-organization. A. N. Alexandrova et al. observed acceleration of Ostwald ripening of sub-nano clusters.
