METHOD FOR FABRICATING COLUMNAR OR LAMELLAR STRUCTURES OF ORGANIC MOLECULES ALIGNED INTO LARGE-AREA SINGLE DOMAIN

Abstract

The present invention relates to a method for fabricating a columnar or layered structure of organic molecules arranged in a large-area single domain, and more particularly, to a method for fabricating a columnar or layered structure of organic molecules arranged in a large-area single domain, in which organic molecules having random arrangement due to their multi-domain structure are spatially confined between a lower substrate and an upper substrate, and then heated above an isotropic transition temperature of the organic molecules, thereby allowing the organic molecules to have a new arrangement different from the original arrangement. The columnar or layered structure of the organic molecules arranged into a large-area monodomain, which is produced by the production method of the present invention, is a large-area monodomain of perfect columnar shape. In addition, since organic molecules are spatially confined between planar substrates regardless of substrate properties and a heat treatment process is performed, the manufacturing method according to the present invention can form nanostructures in a rapid and efficient manner, compared to an alignment method using high temperature or solvent.
