| 摘 要： | 用4-硝基-4′-氨基二苯乙烯-2,2′-二磺酸替代4,4′-二氨基二苯乙烯-2,2′-二磺酸,与三聚氯氰和氨基化合物经过四步缩合得到2个新型不对称结构和用作参比的3个传统对称结构荧光分子。对比研究这两类增白剂在水溶液中的紫外吸收、荧光发射、光致异构化现象及其应用性能。结果显示不对称结构增白剂紫外吸收和染色性能提高,但其荧光发射性能下降,且同样存在较为明显的光致异构化现象,耐光性也较差。 |

| Abstract: | Two new style dissymmetrical and three conventional symmetrical fluorescent brighteners,as the contrastive,were synthesized through four steps of condensation reactions of cyanuric chloride with amino compound and 4-nitro-4-aminostilbene-2,2-disulfonic acid replacing 4,4-amino stilbene-2,2-disulfonic acid.The ultraviolet absorption in aqueous solutions,fluorescence emission properties,photoinduced isomerization phenomena and application properties of the two kinds of FBs were observed.It was found that the ultraviolet absorption and dyeing properties of dissymmetrical FBs increased compared with symmetrical FBs,but the fluorescence emission performance was lower,and at the same time the dissymmetrical FBs had obvious photoinduced isomerization phenomena and its light stability was also low. |
