It is an object of the present invention to provide a polymer that is soluble in an organic solvent with a low polarity and has a high hole injecting property without adding a dopant for enhancing a hole injecting property. For that object, the present invention provides a vinyl monomer represented by the following general formula (1). In the formula, X represents any one of an oxygen atom (O) and a sulfur atom (S). Y represents any one of a hydrogen atom, an alkyl group, aryl group, a silyl group having an alkyl group or an aryl group as a substituent.
本发明的目的是提供一种聚合物,该聚合物可溶于极性较低的有机溶剂中,并具有较高的空穴注入性能,且无需添加用于增强空穴注入性能的掺杂剂。为此,本发明提供了由以下通式(1)表示的
乙烯基单体。式中,X 代表氧原子(O)和
硫原子(S)中的任一种。Y 代表氢原子、烷基、芳基、以烷基或芳基为取代基的
硅烷基中的任意一种。
