Functionalization of BODIPY dyes

Abstract

Boron dipyrrin forms a versatile and significant fluorophore class with enormous photophysical properties, such as excellent photostability and good fluorescence quantum yield, primarily independent of solvent polarity. These properties seek to attract researchers for various applications in biomedical research and as organic photovoltaic devices. In the initial part of this thesis work, the synthesis of 4,4-difluoro-8-(4- methoxyphenyl)-4-bora-3a,4a-diaza-s-indacene along with its -halogenation have described. The resultant molecules can undergo nucleophilic substitution reactions and can be used for coupling with alkyne substituted carbazole, phenothiazine, triphenylamine, etc., which have an excellent scope of applications in diverse research areas. Further, the molecules were characterized by 1H, 13C NMR spectroscopy, and Mass spectrometry techniques.
