Bay‐functionalized [7]Helicene Bilayer Nanographenes (Advanced Optical Materials 13/2026)

Helical Bilayer Nanographene A chiral π-conjugated [7]helicene nanographene forms the central helical scaffold, decorated at the bay positions with butterfly-like chromophores that symbolize tailored functionalization. The composition visually highlights tunable circularly polarized luminescence emerging from helical bilayer nanographene emitters, emphasizing the interplay between molecular helicity, electronic structure, and chiroptical emission.
