Abstract

This work presents a study of the optical properties of polyhydrosilanes in relation with their specific chemical structure. For this purpose, poly[methyl(H)silane‐co‐diphenylsilane] copolymers with a different content of methylhydrosilyl‐segments have been investigated. Steady‐state fluorescence analysis and X‐ray photoelectron spectrometry showed that polyhydrosilanes possess a specific emission profile due to the presence of both methylhydrosilyl segments and silicon nanoparticles within the polymeric matrix. Polyhydrosilanes are capable of generating singlet oxygen reactive species at room temperature. This unusual property was investigated by analyzing the morphological changes in biological systems during Hek293 cell cultures growth in the presence of polyhydrosilanes.

Poly(methyl methacrylate) (PMMA) film was cast from solution in benzene (4% W/V). Various samples of iodine-doped PMMA films were prepared by adding different amount of iodine, namely, 0.5, 1, 2, and 8% (w/w), respectively, to PMMA solution in benzene. The structures of pristine and doped PMMA were
