Microscopic 3D orientation control and photoalignment of liquid crystal copolymer films with N-benzylidenaniline and biphenyl with different terminal substituent

Abstract

Photoalignment of liquid crystal copolymer films with N-benzylidenaniline and biphenyl with different terminal substituent are explored. Control of in-plane and out-of-plane orientation in liquid crystalline polymeric films, which is thermally induced out-of-plane, was investigated by coating low molecular compounds. Furthermore microscopic 3D orientation films are fabricated by coating low molecular compounds by use of inkjet.
