The TACN based gadolinium complex exhibits high two-photon absorption cross-section combined with near-unity 1O2 generation. The very large inter system crossing efficiency induced by the combination of bromine atom and heavy rare-earth element was corroborated with theoretical calculations. The 1O2 generation properties of micellar suspensions under two-photon activation lead to tumour cells death introducing the potential of such structures for theranostic applications
