In this issue, Itamar Willner et al. review dynamic reconfigurable DNA nanostructures, networks, and materials, and Rein V. Ulijn et al. discuss the integration of computation, experiment, and machine learning in the design of peptide-based supramolecular materials and systems. The Minireviews deal with chemoenzymatic cascades that combine biocatalysis and transition metal catalysis for asymmetric synthesis (Vicente Gotor-Fernández et al.) as well as the emergence of covalent organic frameworks as nonlinear optical materials (Bishnu P. Biswal et al.). Sukriyo Chakraborty and Akkattu T. Biju highlight directing-group-free regioselective meta-C–H functionalization of pyridines.

In the original research section, Peter W. Roesky et al. present molecular lanthanide switches for magnetism and photoluminescence (see picture). Anna Donnadio et al. found anhydrous superprotonic conductivity in the zirconium acid triphosphate ZrH₅(PO₄)₃. Yunbin Hu et al. succeeded in the synthesis of a π-extended double [9]helicene. Christopher B. Marshall et al. show how the self-association of the KRAS4b protein is altered by lipid bilayer composition and electrostatics.
