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