Description

technical field

[0001] The present invention relates to a novel organic compound usable as a material for an organic electroluminescence element and an organic electroluminescence element comprising the compound. Background technique

[0002] Starting from Bernanose's observation of organic thin film luminescence in the 1950s, research was carried out on organic electroluminescent (EL) elements developed from the blue electroluminescence of anthracene single crystals in 1965, followed by 1987 In 1999, Tang proposed an organic electroluminescent element with a laminated structure consisting of two functional layers, a hole layer and a light-emitting layer. Afterwards, in order to manufacture high-efficiency and long-life organic electroluminescence elements, the form of introducing each characteristic organic substance layer into the element was developed, and the development of dedicated substances for this was carried out.

[0003] In an organic electroluminescence element...
