applications of carbon monoxide (CO)‐releasingmolecules are limited because they require harmful UV and blue light for activation. We describe two‐photon excitation with NIR light (800 nm)‐induced CO‐release from two MnI tricarbonyl complexes bearing 1,8‐naphthalimide units (1, 2). Complex 2 behaves as a logic OR gate in solution, nonwovens, and in HeLa cells. COrelease, indicated by fluorescence enhancement

properties were studied in detail. Synergistic effects of π–π interactions between GO and the NI chromophore, and efficient photoinduced electron‐ and energy‐transfer processes, were responsible for the strong quenching of fluorescence of these nanoconjugates, which were perturbed under acidic pH conditions, leading to significant enhancement of fluorescence emission. This nanoconjugate was successfully
