Definitions
- the present invention relates to a novel platinum complex that is useful as a material for a light-emitting element that can emit light by converting electric energy into light.
- INDUSTRIAL APPLICABILITY The platinum complex of the present invention is useful as a novel luminescent material that can be suitably used in the fields of display devices, displays, backlights, electrophotography, illumination light sources, recording light sources, exposure light sources, reading light sources, signs, signboards, and intellectuals. is there. Background art
- organic electroluminescent devices (hereinafter referred to as organic EL devices) are promising displays because they can obtain high-luminance light at low voltage. Attention has been paid to such devices as, for example, light emitting devices that form organic thin films by vapor deposition of organic compounds are known.
- This light-emitting element uses a tris (8-hydroxyquinolinato) aluminum complex (hereinafter referred to as Alq) as a fluorescent material as an electron transporting material, and a hole transporting material (for example, an amine compound or the like). By stacking with), the light emission characteristics are greatly improved as compared with conventional single-layer devices.
- the emission process of phosphorescent light is a process in which a molecule is excited from a ground state to an excited state, and then a nonradiative transition called intersystem crossing occurs from a singlet excited state to a triplet excited state.
- the phosphorescence shows luminescence from the triplet state to the ground state. It is expected that high luminous efficiency will be achieved by using the singlet state and triplet state of the organic phosphorescent material. This is thought to contribute to extending the life of the organic EL device.
- An organic EL device using such a phosphorescent material includes phosphorus from a tris (2-phenylvinylidine) iridium complex (I (ppy) 3 ), which is an ortho-metallated iridium complex. Green light-emitting devices utilizing light have been reported (Applied Physics Letters, 75, 4 (1999)).
- platinum complexes include (6-phenyl-1,2,2,1-bividinato-C, N, N) platinum (II) chloride and derivatives thereof (EC Constable et al., J. Chem. Soc. Dalton Trans., 1990, 443-449; Tsz-Chun Cheung et al., J. Chem. Soc. Dalton Trans., 1996, 1645-1651; Yurngdong Jahng et al., In organica Chimica Acta, 267 ( 1998) 265-270 Siu-Wai Lai et al., Inorg. Chem., 38 (1999) 4046-4055). It has been reported that this gold complex exhibits an ultraviolet absorption phenomenon and a fluorescence emission phenomenon.
- Japanese Patent Application Laid-Open Publication No. 2002-175758 does not disclose the external quantum efficiency or the like.
- a metal coordination compound for a light emitting element a cyclic group containing a nitrogen atom is used.
- a platinum complex in which two cyclic groups each containing a carbon atom are coordinated by two each.
- the platinum complexes specifically disclosed herein include those in which all four cyclic groups are independently coordinated to platinum, and those in which only two of the four cyclic groups are bonded. There are three types, one in which it is coordinated to platinum, and the other in which four cyclic groups are each bonded to platinum in a state where two are bonded to each other. There is no disclosure of a complex in which each of the four bonds is coordinated to platinum.
- devices that achieve high-brightness light emission are devices in which organic substances are stacked by vacuum evaporation.However, coating methods are used from the viewpoint of simplification of the manufacturing process, workability, and large area. It is desirable to produce the device by using the above method. However, a device manufactured by the conventional coating method is inferior to a device manufactured by the vapor deposition method, particularly in terms of luminous efficiency, and development of a new luminescent material is desired from such a point.
- the present invention has been made in view of the above-mentioned situation, and provides a platinum complex which is useful as a material for a light-emitting device and has extremely excellent thermal stability, luminous characteristics and luminous efficiency, and an effective production method thereof.
