The present invention provides a 1,3,5-cyclic triazine compound represented by the following formula (1), an organic electroluminescent element that can be driven for a long time using it as an electron transport material, and the compound as an organic electroluminescent element. Applications of constituent components of light-emitting elements. (wherein, Cz represents (n+1) valence carbazolyl or (n+1) valence carboline (these groups may each independently have a fluorine atom or the like as a substituent), Ar 1 and Ar 2 are respectively Independently represents an aromatic hydrocarbon group having 6 to 30 carbon atoms (may independently have a fluorine atom or the like as a substituent), Ar 3 represents an arylene group having 6 to 30 carbon atoms (may have a fluorine atom or the like as a substituent) , Ar 4 each independently represent a nitrogen-containing heteroaryl group with 3 to 30 carbon atoms (which may each independently have a fluorine atom as a substituent), or a substituent represented by the general formula (A), Y and Z each independently Represents a nitrogen atom or CH. Wherein, at least one of Y and Z is a nitrogen atom. n represents an integer from 1 to [the maximum number of bonds that can be formed on Cz-1].) (In the formula, Ar 5 represents (m+1) valent aryl group with 6 to 30 carbon atoms (may independently have a fluorine atom etc. Each independently has a fluorine atom or the like as a substituent), and m represents an integer from 1 to [the maximum number of bonds that can be formed on Ar 5 - 1].) -Ar 5 -(Ar 6 ) m (A). |
