A novel and efficient protocol for the synthesis of amides is reported which employs a BODIPY catalyzed oxidative amidation reaction between aromatic aldehydes and amines under visible light. Compared with the known Ru or Ir molecular catalysts and other organic dyes, the BODIPY catalyst showed higher reactivity toward this reaction. Mechanistic studies reveal that dioxygen could be activated through

Enhanced spatiotemporal selectivity in photonic sensitization of dissolved molecular oxygen is an important target for improving the potential and the practical applications of photodynamic therapy. Considering the high intracellular glutathione concentrations within cancer cells, a series of BODIPY‐based sensitizers that can generate cytotoxic singlet oxygen only after glutathione‐mediated cleavage

The first synthesis of the fully conjugated ethynylene‐linked polymer incorporating boron dipyrrine complex (BODIPY) and zinc porphyrin in the main chain was performed based on the exclusive Sonogashira polycondensation. Comprehensive experimental and theoretical investigations lead to an elaborate synthetic route to circumvent the possible side reactions of BODIPY in the presence of the palladium
mono- and dibromination of 1,3,5,7-tetramethyl-substituted BODIPYs were developed by using copper(II) bromide as the bromination reagent under mild reactions, in good to excellent yields. The selectivity of mono- or dibromination depends strongly on the additives of the reactions. copper - bromination - selectivity - fluorescent dyes - 4,4-difluoro-4-bora-3a,4a-diaza-s-indacenes
