Abstract
The present invention relates to novel polymers which comprise spirobifluorene and fluorine units of the formulae (I) and (II) and may further comprise additional structural elements which may have charge transport properties, hole transport properties and/or electron transport properties. Such materials display a significantly improved property profile in electronic components, particularly when used in a PLED, in particular as electroluminescence material, in 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).
