NITROGENOUS HETEROCYCLIC DERIVATIVE AND ORGANIC ELECTROLUMINESCENT ELEMENT EMPLOYING THE SAME
摘要
<p>A nitrogenous heterocyclic derivative of a specific structure; a material for organic electroluminescent elements which comprises the nitrogenous heterocyclic derivative; and an organic electroluminescent element comprising a negative electrode, a positive electrode, and sandwiched therebetween one or more thin organic layers comprising a luminescent layer, wherein at least one of the thin organic layers consists of the nitrogenous heterocyclic derivative alone or contains the nitrogenous heterocyclic derivative as a component of a mixture. The organic electroluminescent element can have a higher luminance and a higher luminescent efficiency and have a longer life due to improved electrode adhesion.</p>
