Formulation for depositing a light-emitting polymer layer

摘要

The present invention provides formulations which facilitate the direct deposition of patterned polymer films. In particular, the present invention provides a formulation with which polymer films which exhibit improved emission can be uniformly deposited, particularly in the context of relatively high molecular weight polymers with intrinsically rigid conjugated systems. By way of example, a formulation comprising a conjugated polymer dissolved in a solvent comprising at least one substance selected from the group consisting of terpenes and polyalkylated aromatic compounds are demonstrated.
