extended π‐electron molecules contain bulky substituents that shield the vacant boron p orbitals and allow synthetic manipulation and purification under ambient conditions. These borepin‐containing compounds (see picture; Mes*=1,3,5‐tris(tert‐butyl)phenyl; B orange, C gray) display reversible cathodic electrochemistry and can be viewed as n‐type analogues to bent acene hydrocarbons.
不是一个整洁的乙 OH:基于Borepin扩展的π电子的分子包含屏蔽空置硼的p轨道,并允许合成操作和纯化在环境条件下大体积取代基。这些含硼钉的化合物(见图; Mes * = 1,3,5-三(叔丁基)苯基; B橙色,C灰色)显示可逆的阴极电化学,可被视为弯曲并苯烃的n型类似物。
