Epub 2014 Jan 9.A type of BODIPY derivatives was designed and synthesized by the N-alkylation reaction of meso-(4-pyridinyl)-substituted BODIPY. The water-solubility of entire molecule was improved to a large extent as a result of the formation of cationic quaternary ammonium salt, while the strong fluorescence inherent to the BODIPY dye fragment is extinguished on alkylation of the pyridine N atom due to the photo-induced electron transfer (PET) process.
