Abstract

Abstract : Two‐photon excitation with NIR light (800 nm)‐induced CO‐release from two Mn I ‐tricarbonyl complexes bearing 1, 8‐naphthalimide units is reported in this work. One of the complexes obtained behaves as a logic OR gate in solution, nonwovens, and in HeLa cells. CO release, indicated by fluorescence enhancement, was detected in solution, nonwoven, and HeLa cells by single‐ (405 nm) and two‐photon (800 nm) excitation techniques. The photophysical properties of the complexes have been measured and supported by DFT and TDDFT quantum chemical calculations. Both photoCORMs are stable in the dark in solution and noncytotoxic, leading to promising applications as phototherapeutics with NIR light. For more details see the Communication by A. Schiller on page 8453 ff.
