Some implementations provide a composite material that includes a first material and a second material. In some implementations, the composite material is a metamaterial. The first material includes a chiral polymer (e.g., crystalline chiral helical polymer, poly-γ-benzyl-L-glutamate (PBLG), poly-L-lactic acid (PLA), polypeptide, and/or polyacetylene). The second material is within the chiral polymer. The first material and the second material are configured to provide an effective index of refraction value for the composite material of 1 or less. In some implementations, the effective index of refraction value for the composite material is negative. In some implementations, the effective index of refraction value for the composite material of 1 or less is at least in a wavelength of one of at least a visible spectrum, an infrared spectrum, a microwave spectrum, and/or an ultraviolet spectrum.

Provided is a film-forming method based on an LB method by which a uniform alignment film using a helical polyacetylene can be obtained. The method based on the LB method includes: developing a helical polyacetylene onto a liquid surface; and transferring a monolayer film of the helical polyacetylene formed on the liquid surface onto a substrate to form a film, in which a compressibility P represented by the following formula (1) at a time of the film formation is 1×10−2 m/mN or less: P=(1/(dH/dS))×(1/S) (1), where H represents a surface pressure (mN/m) of the monolayer film of the helical polyacetylene, and S represents an area (m2) of the monolayer film of the helical polyacetylene developed onto the liquid surface.

摘要:
The invention relates to a doped polyacetylene film for forming an organic semiconductor or even a conductor of a metallic type. It serves to make the doping more homogeneous and improves the stability over a period of time. The process consists of using as the dopant a salt of an element such as chrome, nickel, iron, titanium, tungsten, or molybdenum belonging to the transition metals, or a salt of an element such as europium or ytterbium belonging to the lanthanides. Doping takes place by immersing the film in a solution having a low dopant concentration, e.g. in toluene, and maintaining the system at low pressure and ordinary temperature for a period of a few days, as a function of the desired doping level and conductivity.
