中文摘要：

在氮气保护、60℃的实验条件下,用水杨酸对聚酰胺-胺树状大分子末端修饰合成了树状大分子PAMAM-S.对其经过荧光分析,探讨PAMAM-S树状大分子的代数、pH值、浓度等影响其荧光强度和光致发光位置的变化.并进一步研究分子力学和动力学性质,结果表明低代PAMAM-S分子空间结构完全是舒展开的,无弯曲现象,分子具有刚性.

英文摘要：

Under nitrogen protect and at 60 ℃ temperature condition,the polyamidoamine dendrimers and PAMAM-S were synthesized respectively by decorated the PAMAM dendrimers on the periphery with salicylic acid.The fluorescent analysis indicated that the PAMAM-S had strongly fluorescent emission and discussed the generation,pH and concentration how to influence fluorescent intensity and emission position of PAMAM-S.And then,its molecular mechanics and molecular dynamics properties were studied.It is found that the mol...
