Novel synthesis of O- and S-doped quadruple helicenes demonstrates enhanced NIR fluorescence, suggesting advances in nanographene design.
O- and S-doped perylene-core quadruple helicenes were synthesized. Heteroatom doping tunes molecular geometry and energy levels, giving NIR absorption and fluorescence with high quantum yield and strong charge-transfer response, advancing chiral nanographene design.
