- W4386202289 abstract "Abstract Self‐assembling features, chiroptical activity, and spin filtering properties are reported for 2,15‐ and 4,13‐disubstituted [6]helicenes decorated in their periphery with 3,4,5‐tris(dodecyloxy)‐ N ‐(4‐ethynylphenyl)benzamide moieties. The weak non‐covalent interaction between these units conditions the corresponding circularly polarized luminescence and spin polarization. The self‐assembly is overall weak for these [6]helicene derivatives that, despite the formation of H‐bonding interactions between the amide groups present in the peripheral moieties, shows very similar chiroptical properties both in the monomeric or aggregated states. This effect could be explained by considering the steric effect that these groups could generate in the growing of the corresponding aggregate formed. Importantly, the self‐assembling features also condition chiral induced spin selectivity (CISS effect), with experimental spin polarization (SP) values found between 35–40 % for both systems, as measured by magnetic‐conducting atomic force microscopy (AFM) technique." @default.
