    摘要： A polymer surface in contact with a liquid crystal medium is exposed to polarized light, whereby a covalently bound anisotropic component of the polymer surface aligns in response to the polarized light. Alignment of the anisotropic component causes alignment of the liquid crystal medium. An interference pattern of two polarized lights causes the covalently bound anisotropic component to form microgrooves on the polymer surface. A liquid crystal cell includes at least one polymer surface that has a covalently bound anisotropic component that can align in response to polarized light and a liquid crystal in contact with the polymer surface.

    摘要： Provided are a polymer containing a thiophene unit and a thienylenevinylene unit, and an organic field effect transistor and an organic solar cell containing the polymer. The film may be formed by coating a substrate with a polymer containing a thiophene unit and a thienylenevinylene unit using a solution process. Therefore, the production cost may be reduced and a large-scale device may be suitably manufactured since there is no need for an expensive vacuum system to form films. Also, the polymer according to one embodiment of the present invention containing a thiophene unit and a thienylenevinylene unit has very excellent flatness since the thiophene unit is continuously coupled with a vinyl group having excellent flatness. Therefore, the polymer may be useful in further improving the charge mobility since it has high crystallinity caused by the improved ordering property between molecules. Such crystallinity may be further improved by the heat treatment. In addition, the organic compound according to one embodiment of the present invention containing a thienylenevinylene unit may have high oxidative stability because of its high ionization energy.

    摘要： An organic solar cell and a method of fabricating the same are provided. The organic solar cell includes a first electrode and a second electrode. An organic active layer is disposed between the first electrode and the second electrode. The organic active layer includes an concave-convex pattern in a surface adjacent to the second electrode. The concave-convex pattern may be formed by contacting an elastomer stamp and a top surface of the organic active layer. The elastomer stamp may be formed by molding using a template having a surface relief grating (SRG). The template may include a photoisomerization polymer layer, and the surface relief grating may be formed by irradiating interference light onto the photoisomerization polymer layer. The surface relief grating may be a blazed diffraction grating.
