Object of the present invention is to provide an organic electroluminescent element having an emissive layer that may be formed by wet process in the fabrication of the organic electroluminescence device with multi-layer structure and has excellent electron-injection property, electron-transfer property, durability and luminescent efficiency and a novel alcohol-soluble organic phosphorescent material that may be preferably applicable to the fabrication of the same. An organic electroluminescent element
1
has a plurality of laminated organic layers
4, 5, 6
sandwiched between anode
3
and cathode
7
. A hole transport layer
5
composed of organic compounds insoluble in alcohol solvent and an emissive layer
6
formed by a wet process so that it contacts with the hole transport layer
5
on the side facing with the cathode
7
contains host materials consisting of one or more phosphine oxide derivatives soluble in alcohol solvent and guest materials soluble in alcohol solvent which can be excited electrically to emit light.

A long-lived near-infrared Nd(III) emission is demonstrated using a Tb(III) donor. The observed emission lifetime of 290 μs at 1057 nm for a Tb(III)–Nd(III) dinuclear complex is attributed to the long-lived Tb(III) donor and the appropriate spacing between the lanthanide ions. This design strategy leads to novel lanthanide photophysics.
使用 Tb( III ) 供体证明了长寿命的近红外 Nd( III ) 发射。观察到的 Tb( III )-Nd( III ) 双核配合物在 1057 nm 处的发射寿命为 290 μs,这归因于长寿命的 Tb( III ) 供体和镧系元素离子之间的适当间距。这种设计策略导致了新颖的镧系元素光物理。
