用相应的硼酸与二胺反应，制备了含有重氮硼酸的新型π共轭体系。它们几乎是无色的化合物，具有供电子的性质。两种化合物的单晶x射线结构分析显示了它们的近平面结构和独特的晶体结构。以透明有机半导体为有源层的FET器件已被成功制备，并表现出良好的p型FET性能。基于该衍生物的FET器件具有较高的HOMO水平，但具有较高的空气稳定性。用XRD和AFM对膜的结构进行了表征。
New π-conjugated systems containing a diazaborole unit have been prepared by the reaction of the corresponding boronic acids with diamines. They are nearly colorless compounds with electron-donating properties. Single crystal X-ray structure analysis of two compounds revealed their nearly planar structures and unique crystal structures. The OFET devices using the transparent organic semiconductors as an active layer have been successfully fabricated and showed good p-type FET behaviour. The FET device based on the derivative showed high air stability in spite of its high HOMO level. The film structures were investigated with XRD and AFM measurements.
