POM images in the a NF and b \({{{\rm{SmC}}}}_{{{\rm{P}}}}^{{{\rm{H}}}}\) phases of 3 in a 5 μm planar aligned parallel rubbed cell. Arrows indicate direction of polarisers and rubbing direction. 2D X-ray scattering images of 3 in the c NF and d \({{{\rm{SmC}}}}_{{{\rm{P}}}}^{{{\rm{H}}}}\) phases. e Temperature dependence of the d-spacing and molecular tilt of 3. Current responses for 3 in the f NF and g \({{{\rm{SmC}}}}_{{{\rm{P}}}}^{{{\rm{H}}}}\) phases. h Microscopy image of 3 with the polarisor inserted parallel to the rubbing direction (no analyser) of the boundary between the NF phase (top) and \({{{\rm{SmC}}}}_{{{\rm{P}}}}^{{{\rm{H}}}}\) phase (bottom) showing selective reflection in the boundary region. i diffraction pattern from the boundary region demonstrating a pitch of  ~ 800 μm. j Transmission spectrum from the boundary region of image (a).
