摘要

Abstract Sequential N ‐alkylations of tetrabenzotetraaza[8]circulene provided mono‐, di‐, tri, and tetra‐ N ‐alkylated products in a controlled manner. Curiously, only opp isomer was obtained as a di‐ N ‐alkylated product. Upon increase of the N ‐alkyl groups, the absorption and emission spectra exhibit continuous red‐shifts, and the excited‐state lifetimes become shortened, probably because of increased steric congestion at the nitrogen atoms that causes the central core to deviate from planarity. Mixed N ‐substituted [8]circulenes have been also prepared.
