AZOBENZENE MOLECULAR MATERIALS CONTAINING SPIROBIFLUORENE AND MANUFACTURING THEREOF

摘要

Azobenzene molecular materials are provided to show a consistent photophysical mass transfer behavior and form rapid optical recording and surface relief gratings because a ratio of azobenzene functional groups contained per a single molecule is high. The azobenzene molecular material containing spirobifluorene has a structure represented by a formula (1) and is prepared by reacting the compound of a formula (11) with amines. In the formula (11), Q represents any one halogen atom selected from Br, Cl, I, and F. A method for forming surface relief gratings in film consists of exposing film to a light, wherein the film is formed of the azobenzene molecular material containing spirobifluorene.
