Optical anisotropy in a new form of crosslinked liquid crystal network
incorporating a fluorescent chromophore has been demonstrated. Linearly
polarised absorption and fluorescence is observed in oriented thin films.
From measurement of absorption and fluorescence anisotropy, the order
parameter was found to be 0.65 and 0.80, respectively. Temperature
dependent birefringence measurements reveal that there is no appreciable
loss of alignment up to 200 °C.
