to vacuum further support the deactivation of a PeT mechanism upon peroxyl radical scavenging by B-TOH. Fluorescence lifetimes and fluorescence quantum yields measured in a range of solvent polarities, from hexane to acetonitrile, for B-TOH, B-BHB, and their BODIPY precursors PM605 or PMOH, are consistent with an intramolecular nonradiativedecay pathway operative in B-TOH. This pathway is not operative
Photocaging facilitates non‐invasive and precise spatio‐temporal control over the release of biologically relevant small‐ and macro‐molecules using light. However, sub‐cellular organelles are dispersed in cells in a manner that renders selective light‐irradiation of a complete organelle impractical. Organelle‐specific photocages could provide a powerful method for releasing bioactive molecules in sub‐cellular

We present a simple, remote sulfonation solution to BODIPY photocages that imparts water solubility and provides control over cellular permeability while retaining their favorable spectroscopic and photoreaction properties. Peripherally disulfonated BODIPY photocages are cell impermeable, making them useful for modulation of cell-surface receptors, while monosulfonated BODIPY retains the ability to
Orthogonally functionalised dendrimers have been constructed by using a versatile approach that is widely applicable for therapeutics and diagnostics by combining imaging agents and therapeutics for synergistic effects. Dendrimers containing a covalently linked dipyrromethene boron difluoride (BODIPY) dye and α‐lipoic acid perform complementary biological functions and target intracellular lipid droplets
