Title:
ORGANIC COMPOUND AND LIGHT EMISSION DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP3508984
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a new compound useful for durable light emission devices capable of high-luminance light output.
SOLUTION: This new compound is an organic compound of formula I [X is a (substituted) arylene or heterocycle; Ar1 to Ar4 are each a (substituted) aryl containing two or more (substituted) fluorenyls], e.g. N,N,N',N'-tetra -[2-(9,9' -dimethylfluorenyl)] -2,7 -diamino-9,9-dimethylfluorene. The compound of formula I is obtained by reaction of a compound of formula II such as 2-iodo -9,9 -dimethylfluorene with a compound of formula III [Ar and Ar' are each a (substituted) fluorenyl or (substituted) aryl] such as 2,7 -diamino-9,9- dimethylfluorene in the presence of a metal catalyst such as copper. This compound of formula I is useful for manufacturing the other objective light emission devices with diversified light emission wavelength exhibiting various light emission hue.
