Synthesis and evaluation of novel meso-coumarin-substituted dithieno[3,2-b]thiophene BODIPY derivatives for photodynamic therapy.
To develop a new photosensitizer for photodynamic therapy featuring strong absorption, high efficacy, and low toxicity, a series of meso-coumarin-modified dithieno[3,2-b]thiophene BODIPY derivatives with tunable side chains were designed and synthesized. These compounds exhibit intense absorption in the 640-730 nm regi...
