Fig. 3. Time-dependent UV-vis absorption spectra for 9,10-anthracenediyl-bis(methylene)-dimalonic acid (ABDA) over (a) TCy5-CHO and (b) TCy5-Btz under 10 mW cm−2 LED light irradiation in ultrapure water. (c) Decrease in the absorbance value of ABDA at 380 nm under NIR LED irradiation. (d) Fluorescence images of MCF7 cells containing TCy5 (5 μM)/SOSG (10 μM), indicating the 1O2 generation of TCy5 dyes upon 660 nm light irradiation with a 20 J cm−2 light dose; for SOSG, emissions are collected at 500–580 nm (λex = 488 nm). Scale bar = 20 μm. (e) Dark toxicity effect of TCy5 compounds on MCF7 cells. (f) Phototoxicity effect of four TCy5 compounds on MCF7 cells under 10 mW cm−2 light irradiation for 10 min.
