The synthesis and
optoelectronic properties of 24 π-electron,
formally antiaromatic fluoreno[3,2-<i>b</i>]fluorene and
fluoreno[4,3-<i>c</i>]fluorene (FF), are presented. The
solid-state structure of [4,3-<i>c</i>]FF along with computationally
analogous molecules shows that the outer rings are aromatic while
the central four rings possess a bond-localized 2,6-naphthoquinodimethane
motif. The antiaromaticity and biradical character of the FFs is assessed
computationally, the results of which indicate the dominance of the
closed-shell ground state for these molecules.
