Molecular superorganizates imply that the structures are designed and arranged in different organic molecules individually, with the result that they reveal a unique phenomenon, an excellent property and something new. LB technique would be useful for constructing molecular superorganizates. A review of the optical properties of organic thin films, such as non-linear optics, photoelectric effects, and photochromism, is presented with this in view. Furthermore, the possibility to control and modify polar structures, molecular interactions, molecular heterojunctions, and photochemical reactions by organizing molecules is discussed.
