Photochemistry and mechanochemistry have been combined to synthesize nanographenes in the complete absence of bulk solvents. The concept is showcased with two reactions—the Mallory reaction and the cyclodehydrochlorination, both applicable to the intramolecular formation of C−C bonds. Moreover, the approach can even form these bonds regioselectively in larger systems—something not possible before in
Chlorine-containing conjugated polymers were obtained by the optimized Stille coupling reaction; non-doped PLEDs of the polymers exhibited NIR emission.
