Research Abstract

We studied the phase and structural transition of smectic thin films in water. As a result, in molecular-order ultrathin films, we found their thinning by one molecular layer on the temperature increase, which has been observed in some particular liquid crystals in air, and also found the difference between our films and such films in air. In addition, we succeeded in preparing spherical ultrathin smectic films. In the films the effect of boundary is fairly less than those in the previous square frame. The phase transition dynamics was observed in the spherical films.
