The invention relates to BODIPY derivatives of Formula (I) that bear one or more functional groups which in the photochemical reaction upon irradiation with visible light undergo deamination and deliver quinone methides. Furthermore, the invention relates to the antiproliferative activity of BODIPY derivatives and their use for pharmaceutical applications and for fluorescent labeling, particularly for labeling proteins.

report the synthesis of unsymmetrical BODIPY dyads through the reaction of phenol oxygen on BODIPYs with α-carbon atoms on bromoBODIPYs. Excited state interactions were observed for the dyads composed of components having similar absorption wavelengths. When dissimilar components were used to construct the dyad, exciton coupling disappeared and an energytransfer causing a large pseudo-Stokes shift was
singlet states, showing unusual anti-Kasha photochemical reactivity. The findings were corroborated by TD-DFT computations. Laser flashphotolysis experiments could not reveal QMs due to the low efficiency of their formation, but enabled the detection of phenoxylradicals. The applicability of the molecules for the fluorescent labeling of bovine serum albumin as a model protein upon photoexcitation
