One electron σ-bonds were first proposed in 1931 but most discussion since then has been at a theoretical level. The first experimentally observed single-electron C–C bond both advances our fundamental understanding of bonding and provides the basis of an approach to creating a new class of molecules.

探索共价的边界


一种电子σ键于 1931 年首次提出，但此后大多数讨论都停留在理论层面。第一个实验观察到的单电子 C-C 键既促进了我们对键的基本理解，又为创建一类新分子的方法提供了基础。
