Abstract
An organic electroluminescent material of the formula:
wherein M is at least one selected from the group consisting of —CH2—, —CH2CH2—, —CH2CH2CH2—, —CH2C(CH3)2CH2—, and —CH2YCH2—, X is at least one selected from the group consisting of oxygen, sulfur, nitrogen, carbon, alkyl, silicon, silyl, phosphorus, aryl, and polyaryl, and n is depending on the amount of free radicals of X. Y is at least one selected from the group consisting of oxygen, sulfur, nitrogen and SiR1R2. Wherein, R1 and R2 is at least one selected from the group consisting of substituted or unsubstituted alkyl having 1 to 10 carbon atoms, and substituted or unsubstituted aryl having 6 to 30 carbon atoms. This invention also discloses an organic electroluminescent element having the organic electroluminescent material.
