| 英文摘要 | A novel trans-7-[4-n, n-di-(beta-hydroxyethylamino-benzene)]-ethenyl-3,5-dinitrothiophene (hbdt) monomer and corresponding prepolymer, polyurethane with the monomer covalently incorporated were synthesized and characterized. the reaction temperature affecting monomer's formation were discussed. since thiophene has a lower delocalization energy than that of benzene, it can offer more effective conjugation and higher nonlinearity than that of benzene in donor-acceptor organic compounds, and forms objective molecules with reasonable optical, thermal stability. the monomer and polyurethane exhibited a good solubility in common organic solvents and thermal stability, the high optical quality films of the polyurethane were fabricated and corona-poled, the uv-vis absorption peaks (530 nm) of the monomer in methanol and the without poling polyurethane films didn't change basically. the second, third-order nonlinear optical susceptibility beta(mu), chi((3)), gamma of hbdt was measured by solvatochromic method and dfwm method, respectively, they were 8.443 x 10(-45) esu, 1.016 x 10(-12) esu (c = 3.96 x 10(-3) mol/l), 3.93 x 10(-32) esu, respectively. |
