A new synthesis and properties of tetrabenzoporphyrin and phthalocyanine

四苯并卟啉（TBP）和酞菁（Pc）是具有平面结构的有机半导体材料，在真空沉积条件下可用于各种电子器件。我们已经成功地用溶液法制备了这种颜料的薄膜。卟啉与双环[2.2.2]辛烷（BCOD）的融合通过热反应转化为TBP。使用该程序，通过旋涂可溶性前体，然后进行热处理来制备TBP薄膜。其显示出场效应晶体管（FET）的良好性能。二甲基基团的引入增加了前体的溶解度，这使得能够通过使用烃溶剂进行旋涂。以类似的方式，制备Pc和石脑油花青（Nc）的可溶性前体，由此通过溶液工艺制备Pc和Nc的FET。

Tetrabennzoprphyrin (TBP) and phthalocyanine (Pc) are organic semiconductors with planar structure, and they have been used for various electronic devices under vacuum deposition. We have succeeded in preparing thin films of such pigments by solution process. Porphyrins fused with bicycle[2.2.2]octadiene (BCOD) are converted into TBP via thermal reaction. Using this procedure, thin films of TBP are prepared by spin coating of soluble precursors followed by thermal treatment. which show good performance of field effect transistor (FET). The introduction of dimethyl groups increases the solubility of the precursors, which enables the spin coating by using hydrocarbon solvents. In a similar way, soluble precursors of Pc and naphtha locyanine (Nc) are prepared, from which FET of Pc and Nc are prepared by a solution process.
