摘要

The present invention provides an organic electroluminescent element and electronic device thereof, wherein the organic electroluminescent element comprises the compound represented by Formula 1 as material for an emission-auxiliary layer, and by comprising the compound represented by Formula 1 in the emission-auxiliary layer, the driving voltage of the organic electroluminescent element can be lowered, and the luminous efficiency and life time of the organic electroluminescent element can be improved.

說明書

Electroluminescence (EL) characteristics were measured with a PR-650 (Photoresearch) by applying a forward bias DC voltage to the organic electroluminescent elements prepared in Examples 1 to 22 of the present invention and Comparative Examples 1 to 5. And, the T95 life time was measured using a life time measuring apparatus manufactured by ms science Inc. at reference brightness of 2500 cd/m2. The measurement results are shown in Tables 4 below.
