Abstract

The invention relates to an optoelectronic device (1) comprising at least one outer surface (2) containing silicone (20), chemical compounds, comprising an anchor group (3) and a head group (4), being bonded to the silicone via the anchor group, and the adhesion of the regions of the silicone (2) present on the outer surface being reduced owing to the head groups of the chemical compounds. A method for producing an optoelectronic device is also disclosed.
