Perylene tetracarboxylic derivatives (PTCDs) display exceptionally high two‐photon absorption (2PA) cross‐ sections (δ, see Figure). In addition, the 2PA saturation behavior and strong two‐photon‐pumped fluorescence suggest that PTCD compounds may be attractive candidates for applications in optical limiting and two‐photon‐pumped upconversion lasing.
