| 摘要:本研究采用三步亲核取代反应，以三聚氯氰和对氨基苯磺酸为原料，4,4-二氨基二苯乙烯-2,2-二磺酸（DSD酸）为发光母体，制备了一种小分子荧光化合物，再利用乙二胺进行聚合反应，制备新型水溶性高分子荧光化合物（EDA-FBs）。结果表明，合成的EDA-FBs荧光量子产率达39％。含质量分数8%的EDA-FBs涂布液涂布后纸张较未涂布纸张白度提高了23.9％，返黄值降低了13.5％，抗张强度提高了58.4％，撕裂度提高了21.9％。 |
| Abstract:In this study， a three-step nucleophilic substitution reaction was used to prepare a small molecule fluorescent compound with cyanuric chloride and p-aminobenzene sulfonic acid as raw materials， and 4，4-diaminostilbene-2，2-disulfonic acid （DSD acid） as luminescent matrix. Then ethylenediamine was introduced to polymerize and prepare a novel water-soluble macromolecule fluorescent compound （EDA-FBs）. The results showed that the yield of synthesized EDA-FBs could be reached 39%， and compared with the uncoated paper， the whiteness of paper after coating with the coating containing 8% EDA-FBs was increased by 23.9%， the yellowing value was reduced by 13.5%， the tensile strength was increased by 58.4% and the tearing strength was increased by 21.9%. |
