Document Type and Number:
Japanese Patent JP3946968
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a blue-luminescent compound containing spirobifluorene and improved in luminescent efficiency and luminance characteristics, a blue- luminescent compound containing a triarylsilylphenyl group, and an organic electroluminescent element using a blue-luminescent compound as a color- developing material.
SOLUTION: A blue-luminescent compound for an organic electroluminescent element is provided which is represented by formula (1) (wherein Ar is a 6-20C aryl group, a 6-20C aryl group having a 1-20C alkyl group, or a 6-20C aryl group having a 1-20C alkoxy group; and R1, R2, and R3 are each H, a 1-20C alkyl group, a 6-20C aryl group having a 1-20C alkyl group, or a 6-20C aryl group having a 1-20C alkoxy group). An organic electroluminescent element using the blue-luminescent compound is also provided.
