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%. |
