ABSTRACT: We
successfully synthesized dithienylethene with amino groups. Then, we
successfully prepared Langmuir-Blodgett (LB) films of the dithienylethene
having ammonium cation group when dodecyl benzene sulfonic acid was employed as
an anionic counter ion. From X-ray diffraction profiles, however, it was
demonstrated that they did not form well-defined layered structure; X-ray diffraction peaks were much
broadened. Photochromic behavior was confirmed in the LB films. Unfortunately,
the LB films were not so stable; photochromic reaction was observed only several times in the LB films.
