abstract = {Two distorted nanographenes combining helicenes
and a fluoranthene unit within their polycyclic scaffolds were
synthesized. Their structural and electronic properties were
elucidated by various spectroscopic methods, and the experimental
data were corroborated computationally. The optical and electrochemical properties of the nanographenes were evaluated. The
compounds exhibit an improved two-photon absorption crosssection compared to their seven-membered ring-containing
counterparts reported previously by us. These results provide
important insights into how the incorporation of a pentagonal ring
affects two-photon absorption properties of nanographenes.
Moreover, one of the nanographenes is chiral and was obtained
enantiomerically pure after chiral separation, allowing the study of
its chiroptical properties both in absorption (electronic circular dichroism) and emission (circularly polarized luminescence).},
