oxadiborepins and the first azadiborepins attained via a modular synthesis route are presented. The new compounds emit intense blue light, some of which demonstrate fluorescence quantum yields close to unity. Cyclic voltammetry (CV) revealed electrochemically reversible one‐electron reduction processes. The weak aromatic character of the novel 1,2,7‐azadiborepin ring is demonstrated with in‐depth theoretical
介绍了通过模块化合成途径获得二噻吩稠合 oxadiborepins 和第一个 azadiborepins 的方法。这些新化合物发出强烈的蓝光,其中一些显示出接近一致的荧光量子产率。循环伏安法(CV)揭示了电化学可逆的单电子还原过程。使用核无关化学位移(NICS)扫描和感应电流密度(ACID)计算的各向异性进行深入的理论研究,证明了新型1,2,7-azadiborepin环的弱芳香特征。
