From: New strategies and implications for the photoalignment of liquid crystalline polymers
Photoresponsive mesogens in a thin film state. Ordinary calamitic (rod-like mesogenic) side-chain polymer films primarily adopt a homeotropic orientation (a), which is unfavorable for electronic excitation by normally incident light. Other strategies are needed to achieve planar orientations of mesogens (b). A full color version of this figure is available at Polymer Journal online.
