A triskelion-shaped saddle-helix hybrid nanographene Moreno Cruz, Carlos Márquez, Irene R. Castro-Fernández, Silvia Cuerva, Juan M. Macoas, Ermelinda González Campaña, Araceli nanographenes helicenes circularly polarized luminescence nonlinear optics A unique rippled nanographene constituted by 52 fused rings is presented in which six out-of-plane motifs are fully fused into a triangular aromatic surface of ca. 2.5 nm size. Three units of an unprecedented fully lateral π-extended octabenzo[5]helicene together with three units of saddle-shaped heptagonal rings are combined in a single structure leading to a well-soluble warped nanographene. The two pairs of possible enantiomers have been isolated and their linear, non-linear and chiroptical properties evaluated, revealing an outstanding quantum yield and brightness values at low energy together with good chiroptical responses both in the absorption and emission 2019-05-21T07:06:45Z 2019-05-21T07:06:45Z 2019-04-10 info:eu-repo/semantics/article Cruz Carlos M.
