The　preparation　of　polycyclic　aromatic　hydrocarbons　(PAHs)　by　the　Scholl　reaction　is　typically　performed　by　using　superstoichiometric　oxidants.　Herein,　we　develop　an　electrochemical　continuous-flow　Scholl　reaction　to　access　PAHs　that　features　a　reduction　in　the　use　of　supporting　electrolytes　and　easy　scale-up　without　changing　the　reaction　conditions　and　setups.　This　reaction　allows　the　synthesis　of　distorted　PAHs　containing　three　[5]helicene　units　that　possess　intriguing　electronic　and　optical　properties.
