The Cover Feature highlights the activation of n–π* transitions in graphitic carbon nitride (g-C3N4). A schematic diagram illustrates the n–π* electronic transition pathways. By facilitating n–π* transitions, the absorption edge of g-C3N4 is successfully extended, enhancing its photocatalytic activity. More information can be found in the Review by Y. Sun, Z. Li, Y. Yuan and co-workers (DOI: 10.1002/chem.202500297).
