Front Cover: Full‐Color Emissive D‐D‐A Carbazole Luminophores: Red‐to‐NIR Mechano‐fluorochromism, Aggregation‐Induced Near‐Infrared Emission, and Application in Photodynamic Therapy (Chem. Eur. J. 11/2023)

Rectangular columns of deep-blue, sky-blue, blue-green, green, yellow-green, yellow, orange and red suggest eight donor–donor–acceptor (D−D-A)-type carbazole derivatives that display full-color emission. The dark red characters being written by pen stand for a red fluorescent luminogen that shows red to near-infrared mechano-fluorochromism. Finally, the light-driven cancer cell death in the inset illustrates how this luminogen also exhibits a photodynamic therapy effect. More information can be found in the Research Article by Z. Chen, Y. Sun and co-workers (DOI: 10.1002/chem.202203797).
