Four novel amine-inserted diphenoquinones have been synthesized as rare examples of para-extended quinones having a heteroatom in the conjugation pathway. The X-ray crystal analysis revealed that all the molecules maintained extended quinoidal structures through the central three-coordinate nitrogen atom. These compounds showed open-shell diradical characters originating from thermally accessible triplet states, and it was demonstrated that the singlet–triplet gaps of this type of molecule could be finely tuned by changing the substituent on the nitrogen atom. More information can be found in the Communication by Daisuke Sakamaki, Akihiro Ito, Shu Seki et al. on page 1889 in Issue 15, 2017 (DOI: 10.1002/asia.201700652).
