THE INFLUENCE OF DEPOSITION CONDITIONS ON THE QUALITY OF THE PHOTOALIGNMENT FILMS OF AZO DYE WITH INTERMOLECULAR BONDS
Abstract
This paper studies the problem of thin layers of azo dyes formation. In particular using spin-coating often leads to formation of tiny crystals in the molecular film, which affects the value of saturated dichroism in absorbing film. The authors suggest Mayer-Rod Coating as an alternative method for deposition of thin films. The film quality was estimated by investigation of the photoalignment dynamics of azo dyes. It is shown that dyes films deposited by rod coating exhibit improved photosensitivity, higher saturation value of the photoinduced absorption dichroism in comparison with the films obtained by spin-coating.
