a Chemical structure and synthesis of D(C7CO)-BTBT from the BTBT π-core via Friedel-Crafts acylation reaction in ambient. b Photos taken during the ambient reaction and the simple work-up (filtering and washing with water/methanol/dichloromethane), and the photo of the gram-scale solid obtained after drying. c Chemical structure of C8-BTBT, experimental HOMO/LUMO energy levels of C8-BTBT and D(C7CO)-BTBT determined via electrochemical methods combined with the optical band gaps (Eg’s)26, and the DFT(B3LYP/6-31 G**)-calculated topographical frontier orbital representations.
