Abstract:
The invention relates to liquid crystalline emitter and charge-transport materials for use in organic light emitting devices. These materials may be used as uncrosslinked liquid crystalline glasses or crosslinked as insoluble polymer matrices. The polymer may be formed by photopolymerization. The polymerization may be done without a photoinitiator. The polymer may have a room temperature nematic phase that may be stabilized the nematic phase relative to smectic phases. The polymer may be easily photocrosslinked with a high final degree of polymerization. The layers of crosslinked layers organic semiconductor may be incorporated into electronic devices. The materials have a high luminous output.
