The semiconductor properties of the earliest known stable radical, α,γ-bisdiphenylene-β-phenylallyl radical (Koelsch radical, 1•) were assessed using spectroscopic and electrical techniques. This radical undergoes reversible redox processes, and it has low redox potentials. In addition, 1• possesses long wavelength absorption bands, owing to the existence of a singly-occupied molecular orbital whose
使用光谱学和电学技术评估了已知的最早的稳定自由基,即α,γ-双二亚苯基-β-苯基烯丙基(Koelsch自由基,1 •)的半导体性质。该自由基经历可逆的氧化还原过程,并且氧化还原电位低。此外,1 •具有长波长吸收带,由于一个单独占领分子轨道,其能级谎言那些HOMO和LUMO之间的存在。1 •的旋涂薄膜显示光电流和6.3×10 -7 cm 2 V -1 s -1的电子迁移率 在一个预制的有机场效应晶体管上。
