Front Cover: Novel Photoinitiators for Two‐Step Absorption‐Based 3D Laser Nanoprinting: From Molecular Design to Printing Behavior (ChemPhotoChem 2/2026)

The Front Cover illustrates the molecular components and 3D printing approach applied in a new study. Photoinitiators, made up a central diketone unit (highlighted in yellow) in combination with the monomer PETA and the scavenger TEMPO, collectively form the photoresist, while blue laser irradiation enables fabrication of the depicted 3D structure.
