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.
