Abstract
(EN)
The present invention provides an organic thin film which enables the achievement of excellent electron injection properties and electron transport properties if used in an electron injection layer of an organic EL element. The present invention relates to an organic thin film which is characterized by: being a single film containing a first material that is a hexahydropyrimidopyrimidine compound having a structure represented by general formula (1) and a second material that transports electrons; or being a multilayer film comprising a film that contains the first material and a film that contains the second material. (In general formula (1), R1 represents an optionally substituted aromatic hydrocarbon group, an aromatic heterocyclic group, an aryl alkylene group, a divalent to tetravalent chain or cyclic hydrocarbon group, a group that is obtained by combining two or more of these groups, or a group that is obtained by combining one or more of these groups and a nitrogen atom; and n represents an integer from 1 to 4.)
