Three series of multifunctional polysiloxane attached with charge-transporting agents and electro-optical chromophores

Three series of multifunctional polysiloxanes containing charge-transporting agents and electro-optical chromophores have been prepared for the photorefractive application. The structural characterization of these polymers is presented by IR, UV, 1H-NMR spectra and elemental analysis. The poled films of polymer 1, 3, 8 reveal resonant d33 values of 21,31 and 19 pm/V by second harmonic generation (SHG) measurements.
