Three-in-one go: One-pot synthesis of isoindole-BODIPY dyes was developed based on nucleophilic substitution (SNAr) reactions of in situ formed chlorinated dipyrromethene by pyrrole. These dyes have long wavelengths, sharp absorption and fluorescence, high fluorescence quantum yields, and high photostability. The wavelength is finely tunable over a wide range (590–714 nm) by variation of substituent groups and functionalization (see scheme).
