Abstract

An organic electronic component is disclosed. In an embodiment an organic electronic component includes at least one organic layer having a fluorinated sulfonimide metal salt of the following formula:

wherein M is either a divalent or higher-valent metal having an atomic mass of greater than 26 g/mol or a monovalent metal having an atomic mass of greater than or equal to 39 g/mol, where 1≤n≤7, and wherein R 1 , R 2 are selected independently of one another from the group consisting of a fluorine-substituted aryl radical, a fluorine-substituted alkyl radical and a fluorine-substituted arylalkyl radical.
