我们合成了一些由氧-1,4-苯基羰基（ArESn, n = 2-4）重复单元组成的芳香酯低聚物作为新型非线性光学（NLO）活性发色团。研究了掺杂10 wt%或5 wt% ArESn和10 wt%对硝基苯胺（pNA）的聚甲基丙烯酸甲酯（PMMA）极性聚合物膜的二级NLO性能。比较这些聚合物薄膜在发色团摩尔浓度[d33(M)]下的d33(M)值表明，ArESn的d33(M)值随n的增加而增加，且当n大于3时，ArESn的d33(M)值高于pNA。此外，每个ArESn的截止波长（λco）约为300 nm，远短于pNA的截止波长（λco=约45 nm）。ArESn是一种很有前途的二阶非线性光学发色团。©1997 Elsevier Science Ltd.
We synthesized some aromatic ester oligomers consisting of repeating units of oxy-1,4-phenylenecarbonyl group (ArESn, n = 2–4) as novel non-linear optical (NLO) active chromophores. Some second-order NLO properties for poled polymer films consisting of poly(methyl methacrylate) (PMMA) doped with 10 or 5 wt% ArESn and 10 wt% p-nitroaniline (pNA) were investigated. Comparison of the d33value at the chromophore molar concentration [d33(M)] for these polymer films indicated that the d33(M) value of ArESn increases with an increase in n and ArESn with n more than 3 reveals a higher d33(M) value than that of pNA. In addition, every ArESn has a cutoff wavelength (λco) of about 300 nm, which is much shorter than the case of pNA (λco= ca.45O nm). ArESn are concluded to be promising chromophores for second-order non-linear optics. © 1997 Elsevier Science Ltd.
