制备了两种新型的分别含有以三苯胺为电子给体的偶氮类发色团作为特征活性官能团和3-呋喃甲酸及受保护的马来酰亚胺的可交联型聚合物体系.通过研究表明利用该制备方法,发色团在聚合物中的含量得到了极大的提高,分别达到32 .1 %( NLO1-P1)和44 .4 %( NLO1-P2) .该聚合物体系以“Diels-Alder”[4 +2]环加成反应作为其交联特征,具有高温非交联、低温交联的特点,其过程与以往的热交联型聚合物相反,可解决传统电光交联聚合物中存在的热交联对极化效率影响的问题并用热失重分析法(TGA)和差示扫描量热法(DSC)分析了这一过程.此外DA交联型聚合物,不需要引入额外的助交联剂,克服了传统热交联聚合物分离难的问题,最大程度的保证了材料的纯度.
Two novel cross-linkable polymer systems containing azo-based chromophores using triphenylamine as the electron donor as the characteristic active functional groups and 3-furoic acid and the protected maleimide were prepared by The results show that the chromophore content in the polymer has been greatly increased by 32.1% (NLO1-P1) and 44.4% (NLO1-P2), respectively, using this preparation method. “Diels-Alder ” [4 +2] cycloaddition reaction as its cross-linking features, with high temperature non-cross-linking, low temperature cross-linking process, the process and the previous thermal cross-linked polymer, The problem of the influence of the thermal crosslinking existing in the electro-optical cross-linked polymer on the polarization efficiency was analyzed by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). In addition, the DA cross-linked polymer, No need to introduce additional co-crosslinking agent to overcome the traditional hot cross-linked polymer separation difficult to ensure the maximum degree of purity of the material.
