High‐Optical‐Quality Ferroelectric Film Wet‐Processed from a Ferroelectric Columnar Liquid Crystal as Observed by Non‐linear‐Optical Microscopy

The self-organization of ferroelectric columnar liquid crystals (FCLCs) is demonstrated. Columnar order is spontaneously formed in thin films made by the wet-process due to its liquid crystallinity. Electric-field application results in high optical quality and uniform spontaneous polarization. Such good processability and controllability of the wet-processed FCLC films provide us with potential organic ferroelectric materials for device applications.
