The present invention provides phthalocyanine nanowires having a minor diameter of 100 nm or less and a ratio (length/minor diameter) of length to minor diameter of 10 or more, an ink composition characterized by containing, as essential components, the phthalocyanine nanowires and an organic solvent, a film including the phthalocyanine nanowires, and an electronic element including a film. Since by using an ink composition containing the phthalocyanine nanowires of the present invention a phthalocyanine film can be formed by a wet process such as coating or printing, a break-proof, lightweight, low-cost electronic element can be provided on a flexible plastic substrate.
本发明提供了小直径为 100 nm 或以下且长度与小直径之比(长度/小直径)为 10 或以上的
酞菁纳米线、一种墨
水组合物(其特征在于作为基本成分包含
酞菁纳米线和有机溶剂)、一种包含
酞菁纳米线的薄膜以及一种包含薄膜的电子元件。由于使用含有本发明的
酞菁纳米线的油墨组合物,可以通过涂布或印刷等湿法工艺形成
酞菁薄膜,因此可以在柔性塑料基板上提供防断裂、轻质、低成本的电子元件。
