Preparation of a Polysilane-(1-Pyrene)Methyl Methacrylate Copolymer

We prepared polysilane–methacrylate copolymers using polysilane as the photoradical initiator. As polymerization is a radical reaction, the chemical structures of the arrangement of the polysilane block and methacrylate have not yet been clarified using various analytical methods. In this study, polysilane–(1-pyrene)methyl methacrylate copolymers were prepared to examine their chemical structure by photoluminescence measurements because the polysilane block and pyrene methacrylate units exhibit fluorescence. The fluorescence analysis revealed the formation of an excimer by the pyrene dimer. From the results, it was found that the pyrene methacrylate units were close to each other.
