顺式二芳基乙烯衍生物、用其的有机电致发光器件和制法
摘要：
本发明提供了式1表示的二芳基乙烯衍生物的有机发光化合物、和使用该有机发光化合物的有机电致发光(EL)器件、和制造该有机EL器件的方法。式中，R1、Ar1、Ar2、Ar3、Ar4、Ar5、Ar6、k、l、m、和n与说明书的定义相同。该有机发光化合物包含与脂族环连接的顺式二芳基乙烯基团，和因此有机发光化合物的结晶不容易发生，和该化合物高度可溶于有机溶剂和容易以有机溶剂提供液体配料。因此，该有机发光化合物可容易用于有机EL器件。使用该化合物制成的有机EL器件可具有热稳定层和因此在优异的接通电压、效率、颜色纯度等方面具有改进的发光性能。
摘要（英）：

Provided are an organic light-emitting compound that is a diarylethene derivative represented by Formula 1, and an organic electroluminescent (EL) device using the organic light-emitting compound, and a method of manufacturing the organic EL device: where R1, Ar1, Ar2, Ar3, Ar4, Ar5, Ar6, k, l, m, and n are the same as defined in the specification. The organic light-emitting compound contains a cis-diarylethene group linked with an aliphatic ring, and thus crystallization of the organic light-emitting compound is unlikely to occur and the compound is highly soluble to organic solvents and easily provides liquid formulation with organic solvents. Thus, the organic light-emitting compound can easily be used in organic EL devices. An organic EL device manufactured using the compound can have a thermostable layer and thus has improved light-emitting properties in term of superior turn-on voltage, efficiency, color purity, etc.
