Schiff base complexes derived from salicylaldehyde and ethylene-, propylene-, and -1,2-cyclohexane-diamines exhibit p-channel transistor properties. The Cu complexes are open-shell compounds, but the oxidation and the hole transport occur at the highest occupied molecular orbital, where the singly occupied molecular orbital (SOMO) does not participate in conduction. Although Ni complexes tend to show larger mobilities than Cu complexes owing to the molecular planarity, the presence of SOMO is not harmful to the transistor properties.
由水杨醛与乙二胺、丙二胺以及1,2 - 环己二胺衍生而来的席夫碱配合物具有p沟道晶体管特性。铜配合物是开壳层化合物，但氧化和空穴传输发生在最高占据分子轨道，其中单占据分子轨道（SOMO）不参与导电。尽管由于分子平面性，镍配合物往往比铜配合物表现出更大的迁移率，但SOMO的存在对晶体管特性并无不利影响。
