Indeno[1,2‐b]fluorenes: Fully Conjugated Antiaromatic Analogues of Acenes

Abstract

What IF? Fully conjugated, formally antiaromatic indeno[1,2-b]fluorenes (IFs; see structure) were synthesized from the corresponding diones by the SnCl2-promoted reduction often used to generate acenes. Their optoelectronic properties suggest that indenofluorenes might serve as alternatives to the more traditionally utilized acenes such as pentacene for materials applications.
