Title:
ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
Japanese Patent JP3163589
Kind Code:
B2
Abstract:
PURPOSE: To obtain the subject element excellent in film thinness and capable of high-luminance emission by incorporating a diolefin compound of a specified formula.
CONSTITUTION: This organic electroluminescent element(EL element) is obtained by using a diolefin compound of formula I [wherein Ar1 and Ar2 are each (substituted)6-20 C aryl; Ar2 is (substituted)6-20 C arylene; R2 is H, (substituted)6-20 C aryl or 1-6 C alkyl; and R1 and R2 may be combined with each other to form a (substituted)saturated five-or six-membered ring, and the substituents include 1-6 C alkyl, 1-6 C alkoxyl, 6-18 C aryloxyl, phenyl, NH2, CN, NO2 and halogen, provided that each of the above groups may have one or more of these substituents] (e.g. a compound of formula II). This EL element is excellent in film thinness and capable of high-luminance emission, so that it can be used in various industrial fields.
