  Electroluminescent Nematic Polymer Networks with Polarised Emission

  摘要：

  Electroluminescence with a polarisation ratio of 12:1 from a uniformly aligned nematic network is reported. Diene photo-active end-groups were used, which polymerise by a selective cyclisation reaction. Surface alignment was achieved for the first time using a doped polymer photoalignment layer, oriented by exposure to polarised UV light. Threshold voltages between 2 V and 8 V were found and a brightness of 90 cd m(-2) was obtained. Both the PL and EL intensities were higher after photochemical crosslinking.

  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.
