摘要:
A cyclometalated transition metal complex emitting phosphorescence of high efficiency and an organic electroluminescent display device employing the same are provided. The cyclometalated transition metal complex has a transition metal atom and a phosphorus ligand having at least one alkylene oxide and a phosphorus atom. The phosphorus atom is bound to the transition metal atom. The cyclometalated transition metal complex can be employed when forming an organic film of an organic electroluminescent display device, can emit light at a wavelength range of 400 nm to 650 nm, and can emit white light as well when used with a green light emitting material and a red light emitting material.
摘要:
An organic electroluminescent device having an emission layer, which is constructed with a host, a phosphorescence emission molecule as a dopant, and a fluorescence supporter. The fluorescence supporter receives energy from the host or traps energy directly, and then transfers the energy to the dopant or self-emits light. An emission spectrum of the fluorescence supporter and an absorption spectrum of the phosphorescence emission molecule overlap partly or completely. The organic electroluminescent device has improved luminous efficiency and color purity characteristics in comparison with a conventional organic electroluminescent device having an emission layer, which is composed of a phosphorescent dopant and a host. This system is useful in the manufacture of, in particular, blue emission devices.

A high-efficient phosphorescent cyclometalated transition metal complex and an organic electroluminescent (EL) device using the same. The transition metal complex can be used in formation of an organic layer of the organic EL device and produce white light emission when used together with a green-emitting material and a red-emitting material as well as emission at the wavelength range of 400-650 nm.
摘要:
A binuclear organometallic complex enabling highly efficient phospholuminescence and an organic electroluminescent device using the same. The binuclear organometallic complex, which can be suitably used to form an organic layer of an organic electroluminescent device, produces luminescence in the wavelength range of 430-650 nm, and induces white electroluminescence when combined with green and red luminescent materials.
