Different from spirobifluorene itself, the LUMO splits although this LUMO splitting is small as compared to that of the HOMO. The carbon nanorings expected to serve as electroluminescent materials, chiral hosts for molecular recognition, and a three-dimensional π-conjugated system based on spiroconjugation for use in charge carrier transport materials. Research directed toward applications as well as further studies of the synthesis of -conjugated systems with a woven-like motif is now underway.
