Fig. 3. (a) Chemical structure of NRh-1 (non-halogenated analogue). (b) Schematic illustration of 1O2 photosensitizing by the heavy atom effect during the one-photon driven upconversion process. (c) DPBF decomposition at 415 nm for different groups. (d) The normalized absorbance changes of DPBF in the presence of FUCP-1 at different temperatures. (e) Confocal fluorescence images of 4T1 cells incubated with DCFH-DA (10 μM) under different treatments.
