Electroluminescent nematic polymer networks with polarised emission

Article abstract of DOI:10.1080/10587250108025021

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.
