摘要：

We systematically designed and developed three novel halogenated aza-octacene derivatives, which have the same pi-conjugated backbone with different terminal halogen groups (F, Cl, Br). These aza-octacene derivatives are synthesized by acid-catalyzed condensation of naphthalene-bisisatin with 4,5-dihalo-1,2-phenylenediamine. The in-depth experimental and theoretical analyses on these molecules, using the non-halogenated system as a reference, allowed us to understand the impact of halogenation on electronic and optical properties. Both electronic affinity (EA) and ionization potential (IP) are...
