Research towards the synthesis of new organic structural themes and the understanding of their physical properties is as important as ever before. In this context metal-free systems have gained increasing interest in the area of materials science for, inter alia, applications in energy conversion (e.g. organic solar cells) or storage (e.g. organic flow batteries). Inspired by our work on bidentate Lewis acid catalysis as well as azobenzene switches we could show that the combination of phenyl-bisborohydride species and azobenzenes furnishes 2,3,1,4-benzodiazadiborinanes in one step, which only have been scarcely investigated. Surprisingly, when benzo[c]cinnolin was used instead of the azobenzene a novel diradical was isolated.In this project, we will systematically investigate the preparation of such stable diradicals and study their properties. Interestingly, upon treatment with pyridine, the diradical is converted into a novel (B–N)2-acene, supporting the feasibility of such structures. Hence, the second part will be devoted to the synthesis of such novel extended (B–N)2-π-systems, which will be not only be of interest for fundamental understanding of polycyclic B,N-heteroaromatics, but also show promise for applications as new materials. The project will be supported by computations.

研究新的有机结构主题及其物理特性的理解一如既往地一如既往地重要。在这种情况下，无金属系统已经对材料科学领域的兴趣越来越多，除其他等外，在能量转化（例如有机太阳能电池）或存储（例如有机流量电池）中的应用。受到我们在边界刘易斯酸催化的工作以及偶氮苯开关的启发，我们可以表明，苯基 - 双苯甲酰基种类和偶氮苯的组合提供了2,3,1,4-苯甲二苯基二苯甲酸盐的一步，仅在一步中进行了很少的研究。令人惊讶的是，当使用苯并[c] cinnolin代替偶氮素蛋白时，将一种新颖的自由基分离出来。在这个项目中，我们将系统地研究这种稳定的尖锐的尖锐的Diradicals并研究其特性。有趣的是，在用吡啶处理治疗后，脏自由基被转化为一种新型（B – N）2-气，支持此类结构的可行性。因此，第二部分将致力于综合这种新型扩展（B – N）2-π系统，这不仅对多环体B，N-杂音异常学的基本理解不仅是感兴趣的，而且还对作为新材料的应用显示了希望。该项目将由计算支持。
