Regioselective direct alkylation of perylene bisimides at 2,5,8,11-positions has been achieved by reaction with terminal alkenes under ruthenium catalysis by the Murai–Chatani–Kakiuchi protocol (see scheme). Alkylation of perylene bisimides results in enhanced solubility and quantum efficiency in the solid state.
