A Stable Triplet-Ground-State Conjugated Diradical Based on a Diindenopyrazine Skeleton
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). With the m-xylylene analogue skeleton containing electron-deficient sp(2)-nitrogen atoms, m-DIP displays significant aromatic character within its pyrazine ring and its spin density mainly delocalizes on the meta-pyrazine unit, making it a triplet ground state conjugated diradical. Our work provides an effective spin density tuning strategy for stable high-spin conjugated radicals.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 22047-25-2. Application In Synthesis of Acetylpyrazine.
