Method for tilted alignment of liquid crystals with improved photostability

摘要: Liquid crystals are induced to assume a uniform tilted alignment in the absence of an applied field by treating surface substrate provide desired microstructure and free hydroxyl groups. A long chain alcohol having formula ROH, where R is carbon at least about 6 atoms therein, chemically reacted with alkoxy groups derived therefrom bonded microstructure. Subsequently introduced liquid tilted-perpendicular tilt angle 0.5° 6°. The exhibit significantly greater photostability than has previously been achieved. preferably obtained depositing sequential layers SiO x medium shallow grazing angles, from 1 2, rotated 90° between depositions.
