英文摘要：

An azobenzene-bridged main chain conjugated polymer was synthesized via oxidation of an aromatic diamine with sodium perborate. The conjugated azobenzene polymer was characterized using FTIR, UV-Vis, DSC, Raman spectroscopy. The number-average molecular weight of the conjugated polymer was 4428 and the glass transition temperature was 186 ℃. Thermal analysis conformed that the cis configuration azobenzene units were on the main chain. When doped with hydrochloride acid, I2, and sodium naphthalide, the electrical conductivities of the conjugated polymer were 8. 7 ×10^-5 S/cm, 2. 65 ×10^-4/cm, and 1.92 ×10^-4 S/cm, respectively. Upon irradiation with W-light, the conductivity increased, subsequently irradiated with vis-light or heated, the conductivity returned to its original levels, which showed that the azobenzene conjugate polymer possessed light modulation conductive properties.
