    • Unlike the Scholl reaction for the synthesis of warped nanographene (ref 13f), a seven-membered ring was not formed in this reaction.

    • Dihedral angles of twisted-1 optimized by DFT calculations are as follows: 28.64° (B3LYP/6-31G(d)), 22.41° (M06-2X/6-31G(d)), 28.90° (BMK/6-31G(d)).

    • As described in some literatures (ref 7a-c, 8b, 8e, 8f), isomerization barriers of double helicenes are known to be higher than those of monohelicene substructures.
