- We report a straightforward synthesis toward pyrrole-cored push-pull single chromophore in which the electron-donating (D) units are pyrrole groups and electron-withdrawing (A) moieties are diketone groups. Optical and electrochemical properties of the novel pyrrole-based building block embedding carbonyl functionalities were studied in detail. On the redox behaviors, this resulting material not only possesses low-lying LUMO but also displays high-lying HOMO with fully reversible p-and n-doping, which can establish it as a good candidate for use as electron/hole-transporting material in optical and electro-optical applications.
