Conventionally, diacetylene or polydiacetylene thin films have been produced by using an organic molecular beam epitaxy (MEB) method or the like. However, since the thin film of diacetylene or polydiacetylene obtained in this manner is polycrystalline composed of particles on the order of microns, it is not effective as a waveguide, for example, due to scattering at the time of optical waveguide. There is also an attempt to obtain a highly oriented film by rubbing the substrate,
Also in this case, there is a problem that the orientation is limited to the horizontal direction with respect to the substrate, and the obtained film is not sufficiently smooth.

Thereby, according to the present invention, the organic MBE method is 1 mm × 1 mm.
A larger area DA or PDA thin film can be epitaxially grown. This epitaxial growth, for example,
It can be performed at a growth rate of 1 to 10 ° / min at a vacuum degree of 10 -8 Torr. At this time, the substrate 5 may or may not be polymerized. However, if the substrate 5 is polymerized in advance, the mechanical and chemical stability of the substrate is improved, and the epitaxial growth can be performed well. The material to be epitaxially grown may be the same as or different from the material of the substrate 5. For example, a formula that is a diacetylene that is difficult to produce good quality crystals by itself: And various other diacetylenes and polydiacetylenes can be epitaxially grown. Further, by introducing a different monomer from a plurality of K-cells, liquid crystal epitaxial growth of a plurality of types of materials can be grown, or a polymer superlattice can be formed.
