A radiation-emitting organic-electronic device is specified. The radiation-emitting organic-electronic device includes a substrate, a first electrode arranged above the substrate, a light-emitting layer arranged above the first electrode, and a second electrode arranged above the light-emitting layer. The light-emitting layer includes a fluorescent compound of a specified formula A. The spacer comprises a linear molecular chain to which two substituents R and R′ are terminally bonded, and at least one group E bonded to the linear molecular chain, wherein E denotes hydrogen and/or an organic radical. The linear molecular chain of the molecules of the fluorescent compound is aligned parallel to the plane of extent of the substrate.
