Red glow in daylight … chemist's delight! An efficient transfer of excitation energy from the ligand to the luminescent states of the coordinated Eu III ion in 1 occurs from the singlet excited state of the ligand. The complex shows characteristic bright red Eu‐centered emission with a quantum yield of 0.52 when sensitized with visible light.
