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