Synthesis of 3,5-Disubstituted BODIPYs Bearing N-Containing Five-Membered Heteroaryl Groups via Nucleophilic C-N Bond Formation.

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.
