A series of novel thiophene-substitutedaza-BODIPY dyes were synthesized by means of a standard procedure and complemented by a Stille-coupling of a brominated species with 2-tributylstannylthiophene. The optical as well as the electrochemical properties of the compounds were investigated and compared to result of density functional theory (DFT) calculations. The influence of the thiophene substituents

In the orignial 1,3,5,7-tetraphenyl aza-BODIPY, replacing the phenyl rings with thiophene achieved significant bathochromic shifts. One of the target molecules, DPDTAB, emitting strong NIR fluorescence with a quantum yield of 0.46 in acetonitrile, is a very competitive NIR fluorophore.
