A novel series of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) dyes bearing polymerizable 4-morpholin-4-yl-benzyl and 4-(dimethylamino)-1-naphthyl groups were synthesized for the first time and further functionalized in a Knoevenagel condensation reaction with 4-(dimethylamino)-1-naphthaldehyde and 4-morpholin-4-ylbenzaldehyde. The identity of BODIPY dyes 1, 2, 4 were confirmed by H-1 NMR, C-13 NMR, FT-IR, UV-Vis and mass spectrometry. Electrochemical characterizations of boron dipyrromethene dyes were carried out with voltammetric measurements. While the 4-morpholin-4-ylbenzyl and 4-(dimethylamino)-1-naphthyl groups substituted BODIPY dyes 1, 2, 3 and 4 gave common reduction reactions during the cathodic potential scans, BODIPY dyes 1, 2, 3 and 4 were electropolymerized on the working electrode.
