| 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%. |
