A novel photothermal therapeutic agent based on a narrow-bandgap benzobisthiadiazole derivative shows strong absorption in the near-infrared region, high photothermal efficiency and robust photostability for treatment of cancer cells.
Benzene-fused bis(acenaphthoBODIPY)s prepared by retro-Diels–Alder reaction of bicyclo[2.2.2]octadiene-fused precursors showed strong absorption bands in the near-infrared region and very weak absorptions in the visible region.
