Synthesis, characterization, optical and electrochemical properties and antibacterial activity of novel BODIPY glycoconjugated dendrimers

Triazole-branched BODIPY glycoconjugated dendrimers are synthesized by click chemistry in good yields via a convergent approach. All glycodendrimers show increase in the fluorescence intensity upon increasing the dendrimer generation. The cyclic voltammograms of dendrimers 1, 2 and 3 show a quasi-reversible behaviour. All the boron-dipyrrolomethene (BODIPY) dendrimers show antibacterial activity against both Gram positive and Gram negative bacteria viz., S. aureus and B. subtilis, and S. typhimurium and E. coli respectively and dendrimer 3 shows a better antibacterial activity than all the other synthesized dendrimers.
