ELECTROLUMINESCENT DEVICES COMPRISING 2-(P-TRIPHENYL)-3-PHENYL-PYRAZINE DERIVATIVES |
摘要 |
<p>Disclosed are electroluminescent devices that comprise organic layers that contain pyrazine compounds. The pyrazine compounds are suitable components of blue-emitting, durable, organo-electroluminescent layers. The electroluminescent devices may be employed for full color display panels in, for example, mobile phones, televisions and personal computer screens. Accordingly, the present invention relates to pyrazine compounds of formula (I), wherein X<1> is a group of formula (II) , or a C16-C3oaryl group, which can optionally be substituted by E, X<2> is an aryl group or a heteroaryl group, which can optionally be substituted, Y<1> and Y<2> are independently of each other a hydrogen atom, C1-C18alkyl, which is optionally interrupted by O, an aryl group or a heteroaryl group, which can optionally be substituted.</p> |
