Dimerized Nitrogen‐Annulated Perylene Synthesized from 1,6‐Diazecine as Chiral Emitter

Abstract

AbstractIn this work, nitrogen‐annulated perylene (NP) was dimerized into one framework connected by two nitrogen atoms, generating the target molecule of DNP−DA. Owing to the substructure of 1,6‐diazecine ten‐membered ring, DNP−DA illustrates helical chirality with moderate dissymmetry factor, elevated molecular levels, expanded conjugation and supramolecular interactions with acceptors etc. Notably, DNP−DA represents a limited example of nitrogen−perylene based CPL emitter with glum around 6×10−3. Intrigued by the facile fabrication via a simple amination‐cross coupling sequence and other above advancing features, this work demonstrates the potential generality of utilizing 1,6‐diazecine as a chiral unit to build CPL‐active materials.
