2023 06 p doping of graphene 1

Phenacenes are known as stable compounds with resistance to oxygen and light, which makes these planar π‑conjugated compounds suitable for utilization as functional materials in numerous applications. The introduction of nitrogen atoms into the phenacene skeleton leads to the formation of a dipole moment which is reflected in modified physicochemical properties when compared to their carbo analogs. Recently, a novel methodology for the synthesis of aza[n]phenacenes (n = 4 – 6) was successfully developed utilizing photocyclodehydrochlorination reaction of starting 2‑chloro-N-aryl-1-naphthamides. Also, a novel N,N-didodecyl‑3,10-diazapicenium salts with bromide and hexafluorophosphate counterions were synthesized as an exfoliant, a stabilizer, and a p‑dopant for liquid phase exfoliated graphene.
