Acceptance is good! 2,8-Disubstituted indeno[1,2-b]fluorenes (see structure; TIPS=triisopropylsilyl) were synthesized and characterized. Electrochemical, optical, and computational data indicate that these electron-accepting hydrocarbons possess low-lying HOMO and LUMO energies, and gap energies that are comparable to common organic n-type semiconducting materials.
