Molecular orientation, molecular packing structure, and electrical properties of thermally stable phthalocyanine, tert‐butylated phthalocyanine (t‐BuPcH₂) in the thin film fabricated by bar‐coating method were investigated. The XRD patterns indicated that the columns composed of t‐BuPcH₂ molecules formed hexagonal structure, the axis of which was parallel to the bar‐sweep direction, and t‐BuPcH₂ molecules were vertically aligned to the bar‐sweep direction. Uniaxially oriented thin films of t‐BuPcH₂ were successfully fabricated on Si substrate covered with polyimide by bar‐coating method, and the field effect mobility of t‐BuPcH₂ was estimated to be 1.32 × 10⁻⁴ cm² V⁻¹ s⁻¹ at maximum. The field effect mobility parallel to the bar‐sweep direction was approximately three times higher than that perpendicular to the bar‐sweep direction due to high electrical conduction along the column axis of t‐BuPcH₂.

单轴溶液涂布法制备叔丁基化酞菁薄膜的分子取向和电性能

研究了通过棒涂法制备的薄膜中热稳定的酞菁，叔丁基化酞菁（t- BuPcH ₂）的分子取向，分子堆积结构和电性能。X射线衍射图谱表明，由t -BuPcH ₂分子组成的圆柱形成六边形结构，其轴平行于条扫方向，t -BuPcH ₂分子与条扫方向垂直对齐。t ‐BuPcH _2的单轴取向薄膜用棒涂法成功地在覆盖有聚酰亚胺的Si衬底上制备了t- BuPcH _2的场效应迁移率，据估计t- BuPcH _2的场效应迁移率最大为1.32×10 ^-4 cm ² V ^-1 s ^-1。由于沿着t- BuPcH ₂的列轴的高电导率，平行于条扫方向的场效应迁移率大约比垂直于条扫方向的场效应迁移率高三倍。
