[Problem] To produce an application-type polysilane composition using polysilane having a high weight-average molecular weight, and provide an excellent silicon thin film having high conductivity after applying the polysilane composition to a substrate and firing the substrate. [Solution] Polysilane having a weight-average molecular weight of from 5,000 to 8,000. The polysilane is a polymer of cyclopentasilane. A silicon film obtained by applying a polysilane composition of polysilane dissolved in a solvent to a substrate, and firing at from 100 degrees to 425 degrees. Polymerization of cyclopentasilane is carried out in the presence of a polymer-supported palladium catalyst. In the polymer-supported palladium catalyst, the palladium of the catalyst component is immobilized by functionalized polystyrene. The palladium comprises a palladium compound or a palladium complex. Immobilization of the palladium involves the microencapsulation of a zero-valent palladium complex or divalent palladium compound using functionalized polystyrene. The zero-valent palladium complex comprises a tetrakis(triphenylphosphine)palladium(0) complex.

The present invention provides a polymer containing thienothiophene, benzothiadiazole and cyclopentadithiophene, a preparation method and an application thereof. The polymer is a polymer P having the following general formula, wherein R1 and R2 are the same or different H or C1-C12 alkyl, and n is a natural number of 5-60. According to the present invention, the three units such as thienothiophene, benzothiadiazole and cyclopentadithiophene in the polymer are combined to form the repeated unit having the acceptor-donor-acceptor-donor (A-D-A-D) form so as to enhance the charge transporting in the polymer molecule, reduce the band gap of the polymer, and expand the light absorption range of the polymer material, such that the polymer has characteristics of excellent sunlight matching property, excellent carrier mobility property and simple and controllable preparation method, and has good application prospects in the fields of polymer solar cells, organic electroluminescent devices and other optoelectronic materials. The polymer P is as the follow.
