Endowing BODIPY PDT agents with the ability to probe lipid droplets is demonstrated to boost their phototoxicity, allowing the efficient use of highly fluorescent dyes (poor ROS sensitizers) as phototoxic agents. Conversely, this fact opens the way to the development of highly bright ROS photosensitizers for performing photodynamic theragnosis (fluorescence bioimaging and photodynamictherapy) from a

A general and straightforward method for the synthesis of COO-BODIPYs from F-BODIPYs and carboxylic acids is established. The method is based on the use of boron trichloride to activate the involved substitution of fluorine, which leads to highyields through rapid reactions under soft conditions. This mildmethod opens the way to unprecedented laser dyes with outstanding efficiencies and photostabilities
Aromatic substitution reactions were applied to the divergent synthesis of a series of symmetrically and unsymmetrically 3,5-disubstituted BODIPYs bearing N-heteroaryl groups. Furthermore, the effect of N-heteroaryl substituents at the 3- and 5-positions on the optical and photophysical properties of the BODIPY π-electron system was elucidated.
Metallic route to antiaromaticity: The synthesis of a butadiyne‐bridged cyclic BODIPY dimer (see structure; C white, B orange, N blue, F green) and trimer was achieved through Pd‐catalyzed Stille coupling and Cu‐mediated Glaser‐type coupling. These cyclic BODIPYs were found to be stable 24π‐ and 36π‐antiaromaticporphyrinoids with planar conformations, and their structures, electronic states, and reactivity
A series of selenophene-substituted boron-dipyrrin (BODIPY) monomers and selenophene-linked BODIPY oligomers was synthesized. The synthesized BODIPYs show good absorption/emission properties in the red to near-infrared region. Furthermore, some of the selenophenyl BODIPYs are not only useful fluorophores but also good photosensitizers to produce singlet oxygen.
