Stable solutions of organic semiconductor materials

摘要

Solutions (I) containing organic semi-conducting compounds comprise at least one solvent and at least one stabilizer comprising a basic compound. An independent claim is included for semiconducting layers containing a compound of formula (1) that are produced from the solutions (I).
