We report the first proof of the ability of octahedral tungsten clusters to emit red-NIR light and to produce singlet oxygen upon two-photon absorption, in solution and in the solid-state. Such discoveries open new perspectives for tungsten cluster compounds in several fields like optoelectronics, photodynamic therapy, and bioimaging.
