  • Patent number: 6998487
    Abstract: 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.

  • Patent number: 6878469
    Abstract: 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.

  • Publication number: 20040170863
    Abstract: Disclosed are double-spiro organic compounds for use in the organic electroluminescence. The double-spiro organic compounds have a configuration or structure including at least three planar moieties, which are substantially linearly configured such that one planar moiety is interveningly located between two neighboring planar moieties and that the intervening planar moiety shares an atom with each of the two neighboring planar moieties. The intervening planar moiety is substantially perpendicular to the two neighboring planar moieties. The two atoms shared with the neighboring planar moieties are preferably most apart from each other in the intervening planar moieties. The double-spiro compounds generally have high melting point above about 300° C. and low crystallinity, which provide thermal stability to the organic EL devices. Also, the double-spiro organic compounds have good sublimability, which provide applicability to the physical vapor deposition.
