An organic EL device employing polymer material includes a structure in which a luminous layer formed of a polymer indicated by
is put between a lower electrode and an upper electrode.
In the above formula, Ar1, Ar2, which can be the same or different, denote arylene groups, R1, R2, R3, R4 denote substituents, and n denotes the copolymerization ratio. The flatness of the luminous layer can be improved and the solubility of the luminous layer constituent material can be enhanced.
一种采用聚合物材料的有机电致发光器件包括一种结构,在这种结构中,在下部电极和上部电极之间有一个发光层,该发光层是由以下字母表示的聚合物形成的
表示的聚合物形成的发光层置于下电极和上电极之间。
在上式中,Ar1、Ar2(可以相同或不同)表示芳基,R1、R2、R3、R4 表示取代基,n 表示共聚比。可以改善发光层的平整度,提高发光层组成材料的可溶性。
