High-spin conjugated radicals have great potential in magnetic materials and organic spintronics. However, to obtain high-spin conjugated radicals is still quite challenging due to their poor stability. We report the successful synthesis and isolation of a stable triplet conjugated diradical, 10,12-diaryldiindeno[1,2-b:2′,1′-e]pyrazine (m-DIP, I, Ar = mesityl, substituted 9-anthryl). With the m-xylylene analog skeleton containing electron-deficient sp2-nitrogen atoms, m-DIP displays significant aromatic character within its pyrazine ring and its spin d. mainly delocalizes on the meta-pyrazine unit, making it a triplet ground state conjugated diradical. Our work provides an effective “”spin d. tuning”” strategy for stable high-spin conjugated radicals.
