    Abstract: 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.

  • Patent number: 8101709
    Abstract: The present invention involves synthesizing conducting polymer nanofibers by mixing an oxidant solution with a monomer solution, which includes a monomer and an oligomer of the monomer that is used as an initiator. The oxidant solution includes an oxidizing agent, or oxidant, such as ferric chloride to oxidize the monomer, the oligomer, or both, and begin polymerization. By including an initiator in the form of the oligomer, which may have a lower oxidation potential than the monomer, the rate of polymerization is accelerated, resulting in the nanofibrous morphology. Therefore, the conducting polymer nanofibers may be synthesized without the use of surfactants, hard templates, or seeds, resulting in a simplified and accelerated polymerization process, which enhances homogenous nucleation of the conducting polymer nanofibers.

  • Patent number: 7834131
    Abstract: The present invention relates to an asymmetric polymer film, in particular based on polazoles, a method for the production of the same and its use. The polyazole-based asymmetric polymer film according to the invention has a smooth and a rough side and enables, on account of its asymmetric structure, rapid and homogeneous doping with acids to form a proton-conducting membrane. The polyazole-based asymmetric polymer film according to the invention can be used in diverse ways on account of its excellent chemical, thermal and mechanical properties and is particularly suitable for the production of polymer electrolyte membranes (PEM) for so-called PEM fuel cells.
