| 摘 要： | 采用小分子联苯甲醛(BPA)分别修饰第一和第二代树状大分子聚酰胺-胺(PAMAM), 合成了2种PAMAM的修饰产物G1-BPA4和G1-BPA8. 利用IR, 1H NMR及MALDI-TOF MS等手段表征了2种产物的结构, 研究了Cu2+浓度对其荧光性能的影响. 结果表明, 在一定的浓度范围内, 作为常见荧光猝灭剂的Cu2+能使2种产物的荧光均显著增强.

| Abstract: | Two PAMAM-BPA dendrimers(G1-BPA4 and G2-BPA8) of generation one and two modified with biphenyl-4-carbaldehyde,were synthesized respectively.These PAMAM-BPA dendrimers were characterized by IR,1H NMR and MALDI-TOF MS.The effects of Cu2+ on the fluorescent properties of these dendrimers was studied.The results indicated that Cu2+ which usually as the fluorescent quenching agent,in proper concentration ranges,could enhance the fluorescence intensity of dendrimer G1-BPA4 and dendrimer G2-BPA8,perhaps due to the presence of the dendrimer effect.It provides a new research content for this kind of dendrimers as the dendrimer-copper hybrid fluorescent materials or as a fluorescence probe of Cu2+. |
