abstract = {We report the synthesis and characterization of an
enantiopure superhelicene nanographene constituted by two saddleshaped
and one planar hexabenzocoronene (HBC) units arranged in
a helicoidal shape. This is, to the best of our knowledge, the first
undecabenzo[7]carbohelicene, i.e., the first fully π-extended
[7]helicene. Racemic resolution allowed its chiroptical properties
analysis revealing dissymmetry factors in the range of 2×10-3 both in
the absorption and in the emission measurements. Remarkably, nonlinear
photophysical analysis showed two-photon absorption crosssection
of 870 GM at 800 nm and a perfect overlapping between linear,
non-linear and chiral emission.},
