dc.description.abstractThis talk will present our synthetic, structural and materials studies of a new class of electron-accepting molecules based on the indenofluorene (IF) skeleton. The initial preparative route involved transannular cyclization of octadehydrodibenzo[12]annulenes to afford the pentacyclic ring system. Subsequent transformations generated the first stable examples of the fully conjugated, 20 pi-electron, formally anti-aromatic compounds.[1] Optimization of intermediate IF-6,12-dione synthesis via a simple three-step process now permits access to IF derivatives in multigram quantities.[2] Work on 6,12-diarylIFs demonstrated that single crystals of the pentafluorophenyl derivative could serve as an active layer in organic field effect transistors (OFETs) that exhibit ambipolar behavior using Au source/drain contacts.[3] Current studies are focused on varying the antiaromaticity of the indacene unit by replacement of the benzene groups with thiophene units[4] as well as increasing biradical character of the framework by expansion of the quinoidal core.[5] [1] Chase, D.
