摘要： The present invention addresses the problem of providing: a composition for electronic devices in which when a film is formed therefrom, the amount of residual solvents including fluorine-containing solvents within the film is reduced, the effects of residual solvents on a device are minimized, and it is thus possible to achieve high element performance; an ink for electronic devices that is suitable for wet processes and that makes it possible to achieve high liquid stability and element performance as a result of containing the composition for electronic devices; and a method for producing an electronic device. This composition for electronic devices contains a component A and a component B and is characterized in that the component A is a fluorine-containing solvent and the component B is a compound having a structure represented by general formula (1).

摘要： An organic electroluminescent element includes a hole injection layer (HI), a first hole transport layer (HT1), a second hole transport layer (HT2), and a light-emitting layer containing a host compound (H) and a phosphorescence emitting dopant compound (D), which are laminated in this order, between and an anode and a cathode. The phosphorescence emitting dopant compound has a partial structure represented by Formula (1): The “highest occupied molecular orbital” HOMO of the second hole transport layer satisfies the expression: −5.4 0.1.
