ORGANOSILICON FILMS WITH MOLECULAR MICRORELIEF TO ALIGN LIQUID CRYSTALS
Abstract
New organosilicon compounds on the base of both cyclic and linear siloxanes
with different structure of the substituents have been created and performances of the LC
anchoring on OC films have been measured. The OC studied provide the homogeneous
planar alignment with LC tilt angle in the range from 0.7° to 1.9°. An increase of the microrelief
depth results in a small increase of the tilt angle. The azimuthal anchoring is better
for the films of the OC without molecular microrelief or the OC comprising polar
groups.
