a ESR spectra demonstrating 1O2 generation of [Ru(bpy)3]2+ under US irradiation (0.3 W cm−2, 3 MHz, 1 h). The TEMP and DMPO were used as 1O2 and •OH trapping agents, respectively. b Time-dependent oxidation of DPA indicating 1O2 generation by [Ru(bpy)3]2+ under US irradiation (0.3 W cm−2, 3 MHz). c Time-dependent 1O2 generation of [Ru(bpy)3]2+ detected by fluorescence intensity of SOSG under US irradiation (0.3 W cm−2, 3 MHz). The colored lines represent spectra recorded every 10 min for 100 min in (a) and (c). Ru: [Ru(bpy)3]2+. TEMP: 2,2,6,6-tetramethylpiperide; DMPO: 5,5-dimethyl-1-pyrroline-N-oxide.
