Twisted Molecular Nanoribbons with up to 53 Linearly-Fused Rings


The synthesis of three molecular nanoribbons with a twisted aromatic framework is described. The largest one shows a 53 linearly fused rings backbone (12.9 nm) and 322 conjugated atoms in its aromatic core (C296N24S2). This new family of nanoribbons shows extremely high molar absorptivities, reaching 986 100 M-1 cm(-1), and red-emitting properties.
