C₆₀-styryl Bodipy dyads that show strong absorption of visible light (蔚 = 64鈥?00 M^鈥? cm^鈥? at 657 nm) and a long-lived triplet excited state (蟿_T = 123.2 渭s) are prepared. The dyads were used as heavy-atom-free organic triplet photosensitizers for photooxidation of 1,5-dihydroxynaphthalene via the photosensitizing of singlet oxygen (¹O₂). The photooxidation efficiency of the dyads compared to the conventional Ir(III) complex ¹O₂ photosensitizer increased 19-fold.
