ANTHRACENE DERIVATIVE, AND LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, ELECTRONIC DEVICE USING ANTHRACENE DERIVATIVE

An object is to provide a novel anthracene derivative. Another object is to provide a light-emitting element with high luminous efficiency. Yet another object is to provide a light-emitting element with a long lifetime. Still another object is to provide a light-emitting device and an electronic device having a long lifetime by using the light-emitting elements of the present invention. The anthracene derivative represented by General Formula (1) is provided. The ability of the anthracene derivative represented by General Formula (1) to exhibit high luminous efficiency allows the production of a light-emitting element with high luminous efficiency and a long lifetime.

Double-spiro organic compounds and organic electroluminescent devices using the same

Disclosed are double-spiro organic compounds and an organic electroluminescence (EL) device using the same. The double-spiro organic compounds are configured to have at least three planar and substantially linear moieties, such that one planar moiety is located between two neighboring planar moieties and that the intervening planar moiety shares an atom with each of the two neighboring planar moieties. The double-spiro compounds generally have high melting point above about 300 degree C. and low crystallinity, which provide thermal stability to the organic EL devices. These organic compounds have good sublimability. They also have light-emitting, hole-injecting, hole-transporting, electron injection, electron-transporting properties and characteristics, which are favorable in the organic EL devices.

NEW MATERIAL FOR TRANSPORTING ELECTRONS AND ORGANIC ELECTROLUMINESCENT DISPLAY USING THE SAME

Novel materials for electron injection/transportation and emitting layers can greatly improve the stability of an organic electroluminescent display. Electroluminescent displays incorporating these materials produce blue light at low voltage levels. These novel organic materials include compounds in which 1 to 2 imidazole functional groups are introduced in the 2 or 2,6-site of 9,10 substituted anthracene. An organic electroluminescent display with an organic compound layer of these materials has high efficiency, thermal stability, operationally stability and maintains driving voltage before and after operation.
