Red glow in daylight ... chemist's delight! An efficient transfer of excitation energy from the ligand to the luminescent states of the coordinated EuIII ion in 1 occurs from the singlet excited state of the ligand. The complex shows characteri

Three triazine-based europium(III) complexes were synthesized that demonstrated strong two-photon induced europium emission with a high two-photon absorption cross-section. The modified triazine ligand of complex 3 initiated over 100% enhancement of the two-photon absorption cross-section (σ2: 320 GM) when compared with complex 1 (σ2: 128 GM) in a solution of DMSO. Europium complex 3 is also stable in vitro, and power-dependence curves were obtained in vitro to confirm the two-photon-induced f-f emission in HeLa cells.
