-bridges have better power conversion efficiency and higher device stability. The device based on the quaterthiophene-bridged compound 4 gave a highest power conversion efficiency of 5.62% with a VOC of 0.93 V, JSC of 9.60 mA·cm−2, and a FF of 0.63.
Keywords: A–π–D–π–A-typeconjugatedmolecules
molecular structure and properties of the conjugated molecules with BDT core, we report here a series of A–π–D–π–A-typeconjugatedmolecules with a regioregular oligo(3-hexylthiophene) chain as the π-bridge unit. The optical and electrochemical properties of these compounds were systematically investigated
