Outside Back Cover: Photoredox Autocatalysis: Towards a Library of Generally Applicable Reductive Photocatalysts (Angew. Chem. Int. Ed. 22/2025)

Biarylsultams as self‐synthesizing autophotocatalysts are represented as repeating tile patterns on mosaic lamps, with different coloured lamps representing different substituted biarylsultam derivatives. Reflecting the self‐synthesizing library concept, the lamps are suspended within a library. On the spines of the books are imprinted the photocatalytic synthetic transformations exemplifying the reductive power of biarylsultam organophotocatalysts, as demonstrated by Joshua P. Barham et al. in their Research Article ( e202423190 ).
