Synthesis, optical and electrochemical properties, and photovoltaic performance of a panchromatic and near-infrared (D)<sub>2</sub>–π–A type BODIPY dye with pyridyl group or cyanoacrylic acid
that the two BODIPYdyes show two reversible oxidation waves, thus indicating that the redox processes of OMK-PY and OMK-CA are very stable. On the basis of the experimental results and density functional theory calculation, we propose that the (D)2–π–A BODIPY structure with two diphenylamine–thienylcarbazole moieties as strong electron-donating units at the 3- and 5-positions on the BODIPY core is an
Sequence‐independent or “click”‐type chemistry is applied for the preparation of novel π‐conjugated oligomers. A variety of bi‐functional monomers for Wittig–Horner olefination are developed and applied in a sequential protection–deprotection process for the preparation of structurally similar π‐conjugated oligomers. Selected oligomers are incorporated as the organic semiconductors in light‐emitting
photoactive arrays consisting of Bodipy scaffoldings is described. The syntheticstrategy involved first the construction of functionalised modules, then the use of specific Knoevenagel reactions. Boron-protection is required to avoid self-condensation. Comparison of thienylBodipy dyes with their phenyl analogues showed them to be both less chemicallystable and more weakly fluorescent. In the multichromophoric
