Abstract

An organic electroluminescence device having at least one organic layer between a pair of electrodes is provided. The organic layer contains a compound represented by formula (I), Z1 and Z2 each represent a nitrogen-containing aromatic 6-membered ring coordinated to a platinum atom at a nitrogen atom, and Q represents a nitrogen-containing aromatic ring with one or two nitrogen atoms. In a 5-membered ring, L1 and L2 each represent a single bond or a divalent group, and n represents 0 or 1.

Description

technical field [0001] The present invention relates to a platinum complex used as a luminescent material and to an organic electroluminescent device using the same. Background technique [0002] An organic electroluminescent device can be driven at a low voltage to provide high-intensity light emission, and thus has been actively researched and developed. An organic electroluminescence device has an organic layer sandwiched between a pair of electrodes, in which electrons injected from a cathode and holes injected from an anode recombine to generate excitons, and light is emitted using the energy of the excitons. [0003] In recent years, the use of phosphorescent materials has led to improvements in the luminous efficiency of the devices. As light-emitting materials, iridium complexes or platinum complexes are known (see, for example, US Pat. No. 6,303,238 and WO 00 / 57676 pamphlet). However, an element capable of exhibiting both high luminous efficiency and high durabili...
