Synthesis and photorefractivity of polysiloxanes bearing hole-conductors doped with a nonlinear optical chromophore

New polysiloxanes-based hole-transporting polymers have been synthesized and characterized. The polymer possesses an N-phenyl-N-propylphenanthren-9-amine (PSX-PhPA) and 3-((2,2-diphenylhydrazone)methyl)-1-propyl-1H-indole (PSX-IDEH). Our results show that the photoconductivity, diffraction efficiency, and photorefractive response time were found to be 0.458 pS/cm, 54.9%, and 7.8 s for the PSX-PhPA composite and 1.044 pS/cm, 41.7%, and 5.47 s for the PSX-IDEH composite at wavelength of 633 nm.
