This book describes the various methods currently used to deposit highly ordered organic films, and the physical techniques employed in characterizing their properties. Beginning with a discussion of the necessary basic physics and chemistry, the book proceeds to a description of the main topics of current research in this field. The author discusses in detail the Langmuir-Blodgett technique, self-assembly, and methods of film deposition exploiting the ordered structure of mesophases. Finally, he treats liquid crystals, films at the air/water interface and biomembranes.
