摘要： The supported catalyst according to the present invention comprises a support of organic or inorganic powder with a high-surface area, a polymer coated onto the support and a metallocene catalyst. The polymer (1) contains polar groups; (2) interacts with the surface of the support; and (3) is insoluble in the styrenic monomer or polymerization solvent during polymerization after the catalyst is loaded. The polymer is located between the support and the metallocene catalyst such that the polymer insulates the metallocene layer from the support layer to prevent poisoning of the metallocene catalyst layer by the support layer. The styrenic polymer powder such produced by the present invention has good flow-ability and good morphology demonstrating a great deal of industrial applicability.

摘要： The present invention relates to a 2,7-carbazole-containing polymer represented by formula 1 and an organic photovoltaic device comprising the conductive polymer as a photoelectric conversion material. The conductive polymer has high photon absorption efficiency and improved hole mobility and is prepared by introducing a specific amount of a carbazole compound either into a polymer, consisting only of a donor functional group containing one or more aromatic monomers, or into a donor-acceptor type polymer comprising a repeating acceptor group introduced into a donor functional group. The conductive polymer can be used as a photoelectric conversion material for organic thin film transistors (OTFTs) or organic light-emitting diodes (OLEDs). Furthermore, the invention provides an organic photovoltaic device comprising the carbazole-containing conductive polymer as an electron donor, and thus can achieve high photoelectric conversion efficiency in organic thin film solar cells.

摘要： The present invention relates to a pyrene-containing conductive polymer represented by formula 1 and an organic solar cell comprising the same as an organic photovoltaic material. The conductive polymer has improved hole mobility as a result of introducing a specific amount of pyrene either into a polymer, which consists only of a donor functional group comprising one or more aromatic monomers, or into a donor-acceptor type polymer comprising a repeating acceptor introduced into a donor functional group. Thus, the conductive polymer can be used as an organic photovoltaic material in organic photodiodes (OPDs), organic light-emitting diodes (OLEDs), organic thin-film transistors (OTFTs), organic solar cells and the like. In addition, an organic solar cell showing high power conversion efficiency (PCE) can be provided using an organic photovoltaic material comprising the pyrene-containing conductive polymer as an electron donor.
