Title
Synthesis, photoconductivity, and photogeneration efficiency of polysiloxanes bearing hole-conductors for photorefractive materials
Abstract

Two series of polysiloxanes, namely, PSX-DCZ and PSX-TPD, with hole-transporting moieties have been synthesized and their electronic absorption, electrochemical behavior, quantum efficiency of charge generation, and photoconductivity is also studied. Our results show that the photocurrent were found to be ca. 3280 nA for PSX-DCZ/C60 and ca. 3400 nA for the PSX-TPD/C60 at wavelength of 633 nm and an electric field of 60 V/μm. We also obtained the quantum efficiency of charge generation as high as 25.2 × 10−5 for PSX-DCZ/C60 and 31.1 × 10−5 for PSX-TPD/C60 (at λ = 633 nm, E = 60 V/μm). The photoconductivity of these polymers is found to be greater than that of PVK/C60.
