Abstract Functional photoactive polysilane copolymers of poly(methylphenylsilane) (PMPS) and disperse
yellow 7 methacrylate (DY7MA) were synthesized using UV-technique. In the same manner
functional polysilane copolymers of poly(methylphenylsilane-co-dimethylsilane) (CPS) and
disperse yellow 7 methacrylate (DY7MA) were also synthesized. By the UV irradiation polysilanes
(PMPS and CPS) give rise to silyl macroradicals which initiate the polymerization of photoactive
monomer (DY7MA). The synthesized samples were characterized by FTIR, NMR, and UV-Vis
spectroscopy. The molar mass of synthesized photoactive functional polysilane copolymers is
of order of 103
gm/mol. They exhibited multimodal optical and photoluminescence functional
properties. Optical absorbance was observed at 336 nm due to… More >
