Abstract: High Resolution Image Download MS PowerPoint Slide This study presents an efficient method for synthesizing twisted benzo-extended [ n ]phenacenes ([ n ]BPs) featuring an electrochemical flow (e-flow) Scholl reaction of the corresponding [ n ]BP precursors from a one-pot three-component Suzuki–Miyaura coupling reaction. The e-flow Scholl reaction offers advantages such as reduced oxidant usage and overoxidation byproducts, and easy scale-up through extended electrolysis time toward these intricate polycyclic aromatic hydrocarbons. In addition, the increase in molecular length decreases the optical bandgap of [ n ]BPs and thus tunes their photophysical properties. This work provides a green and sustainable synthetic strategy for diverse [ n ]BPs and enables facile bandgap modulation through π-conjugation extension, offering potential for organic semiconductor applications in optoelectronic devices.
