From: J-aggregates of meso-[2.2]paracyclophanyl-BODIPY dye for NIR-II imaging
Fluorescence spectra of PCP-BDP1 (a) (10 μM) and PCP-BDP2 (b) (10 μM) in THF-water binary solvents varied fw. Fluorescent spectra of PCP-BDP1 ((c), excited at 480 nm) and PCP-BDP2 ((d), excited with 808 nm laser) in the crystalline powder state. e TEM images of PCP-BDP2 NPs. The results are representative of three independent experiments. f The particle size distribution of PCP-BDP2 NPs measured by DLS with a PDI of 0.081. g Normalized absorption and emission spectra of PCP-BDP2 NPs in PBS solution. h Normalized emission decay of PCP-BDP2 NPs and IR1061 at their emission maxima under laser irradiation (808 nm, 100 mW/cm2, 60 min) for different irradiation times. Source data underlying (a–d, f–h) are provided as a Source data file.
