Free-standing ultra thin films of ferroelectric liquid crystal of 7nm to 150nm in thickness have been prepared. The structure and electro-optical properties of these free-standing films have been studied by means of ellipsometry and electro-optical measurements. The Sm A and Sm C∗ phases have been observed in the free-standing films. The phase transition temperature between the Sm A and Sm C∗ phases has shifted to higher temperature with decreasing thickness of free-standing film. The molecular tilt angle in the induced Sm C∗ phase of free-standing film is independent of the thickness of the film and is smaller than that of bulk. The electro-optical response has been observed in the Sm C∗ phase of this free-standing film.
