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.
