LIQUID COMPOSITION FOR DEPOSITION OF ORGANIC ELECTROACTIVE MATERIALS

摘要

Compositions are provided for improved liquid deposition of electroactive material onto low surface energy layers. The liquid composition includes at least one organic electroactive material in a liquid medium. The liquid medium includes (a) at least 20% by volume, based on the total volume of the liquid medium, of a first solvent and (b) at least 1% by volume, based on the total volume of the liquid medium, of a liquid organic additive. The liquid medium pins on the underlying layer as determined by a dynamic receding contact angle test. The first solvent retracts on the underlying layer as determined by the dynamic receding contact angle test.
