Abstract: This chapter focuses on the synthesis, structural, optoelectronic and materials properties of redox-active, fully conjugated indenofluorenes (IFs), and several other structurally related compounds containing only sp2 hybridization at the bridgehead of the five-membered rings. IFs are composed of five structural isomers: indeno[1,2-a]fluorene, indeno[1,2-b]fluorene, indeno[2,1-a]fluorene, indeno[2,1-b] fluorene, and indeno[2,1-c]fluorene. In addition to studying the effects of increased core conjugation, the synthesis of fluoreno[4,3-c]fluorene skeleton could be used to study the limits of the SnCl2 mediated reductive dearomatization. Quinodial thiophenes have attracted a good deal of attention recently due to their ease of synthesis and promising use in functional materials. In an analogous manner to the indacenedithiophenes (IDTs), the Haley and Chi labs have also explored replacing the inner benzene ring of IFs with the isoelectronic thiophene unit to create the diindenothiophenes (DI[n]Ts).
