Abstract

The present invention relates to a process for producing particle-free solutions of polymeric semiconductors and to their use for producing layers of polymeric semiconductors in polymeric organic light-emitting diodes (PLEDs), organic integrated circuits (O-ICs), organic field effect transistors (OFETs), organic thin film transistors (OTFTs), organic solar cells (O-SCs) or organic laser diodes (O-lasers).
