Poly(silylene)s: Effect of polar acceptor side groups on the charge carrier photogeneration and transport
The influence of polar electron-acceptor chromophores (both admired and covalently bonded to the polymer backbone) on photoelectrical properties of poly[methyl(phenyl)silylene] was studied. Whereas the charge carrier mobility decreased for any concentration of the chromophore, the photogeneration efficiency increased for concentrations up to about 4 more %. For higher concentrations, some decrease was observed. The decrease in mobility was ascribed to the electron-dipole interaction and to the broadening of the density-of-states distribution affecting the hopping transport.
