摘要:
The present invention provides an organic thin film that imparts an excellent electron injection property and an excellent electron transport property when it is used as an electron injection layer of an organic EL device, a coating composition suitable for producing the organic thin film, and an organic EL device material for the organic thin film and the coating composition. The present invention provides an organic thin film, which is a single film containing a first material which is a compound having a structure of the following formula (1) and a second material which transports electrons or a laminate film including a film containing the first material and a film containing the second material,
wherein X 1 and X 2 are the same as or different from each other and are each a nitrogen atom optionally having a substituent group, an oxygen atom optionally having a substituent group, a sulfur atom optionally having a substituent group, or a divalent linking group optionally having a substituent group; L is a direct bond or a linking group having a valence of p; n is a number of 0 or 1; p is a number of 1 to 4; q is a number of 0 or 1, with q being 0 when p is 1; R 1 to R 3 are the same as or different from each other and are each a monovalent substituent; and m 1 to m 3 are the same as or different from each other and are each a number of 0 to 3.
