    摘要: A composition capable of emitting circularly polarised light comprises a medium including a chiral, helical liquid crystalline phase with a substantially fixed, temperature independent helical pitch. The liquid crystalline phase is comprised of calamatic liquid crystal molecules having a luminescent moiety and the composition is such that excitation of the luminescent moiety causes the medium to emit light in the bandwidth of selective reflection of the liquid crystalline phase. To achieve the substantially temperature independent helical pitch, the chiral helical liquid crystalline phase may be in the form of a glass or a polymerised network. The composition may be used to produce a light emitting device, e.g. and OLED.

    摘要: 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.
