Synthesis, structure, and physicochemical properties of singlet biradical oligomers

几种p -杂环单线双基可以在室温下在空气中处理，这对于探索新材料是理想的。本文成功地合成了包含两个和三个双基单元的低聚（双基）化合物，它们是稳定的晶体化合物，并且在双基单元之间表现出明显的跨空间相互作用。这些发现表明，单线态双自由基有望开发出不积累π共轭平面结构的分子电子学新材料。

Several P-heterocyclic singlet biradicals can be handled in the air at ambient temperature, which is desirable for exploration of novel materials. Oligo(biradicals) containing catenated two and three biradical units were successfully synthesized as stable crystalline compound, and showed considerable through-space interaction between the biradical units. These findings indicate that the singlet biradicals are promising to develop novel materials for molecular electronics without accumulation of π-conjugated planar structures.
