A New Trend in Phenalenyl Chemistry: A Persistent Neutral Radical, 2,5,8-Tri-tert-butyl-1,3-diazaphenalenyl, and the Excited Triplet State of the Gablesyn-Dimer in the Crystal of Column Motif
derivative, which produces a perimidine framework, nitrogen‐dopednanographenes were realized. Two nanographenes produced by a one‐pot reaction of edge‐oxidized nanographene (GQD‐2) with 1,8‐naphthalenediamine derivatives (GQD‐1 a and GQD‐1 b) displayed an absorption band extending to >1000 nm; furthermore, the PL wavelength of GQD‐1 a was significantly red‐shifted into the near‐infrared (NIR) region in
