Abstract Imide functionalization has been widely proved to be an effective approach enrich optoelectronic properties of polycyclic aromatic hydrocarbons (PAHs). However, appending multiple imide groups onto linear acenes is still a synthetic challenge. Herein, we demonstrate that by taking advantage “breaking and mending” strategy, pentacene tetraimides (PeTI) was synthesized through three‐step sequence started from the naphthalene diimides (NDI). Compared with parent pentacene, PeTI shows deeper‐lying lowest unoccupied molecular orbital (LUMO) energy level, narrower band gap better stability. The redox behavior firstly evaluated generating stable radical anion specie assistance cobaltocene (CoCp 2 ), structure electron transfer (ET) complex confirmed X‐ray crystallography. Moreover, due presence redox‐active sites, are able show state‐of‐the‐art storage performance dealkylated (designated as PeTCTI) in organic potassium ion batteries (OPIBs) anode. Our results shed light on application imides functionalized acenes, reported strategy provides way get access longer nanoribbon fascinating electronic properties.
