ELECTROLUMINESCENCE ELEMENT |
摘要 |
<p>An electroluminescent device comprising an anode, a cathode, and at least one electroluminescent organic layer interposed therebetween, wherein a luminescent material in the organic layer emits light upon application of a voltage between the anode and the cathode, is characterized in that a salt of an electron accepting dopant with a polyimide precursor and/or polyimide having oligo-aniline units on side chains is formed as an auxiliary carrier transporting layer between the anode and the organic layer, the polyimide precursor and/or polyimide being obtained from a diamine component containing at least 1 mol % of an oligo-aniline unit-bearing diaminobenzene derivative and a tetracarboxylic dianhydride or derivative thereof.</p> |
