| 摘 要： | 以小分子2-芴醛(FCD)修饰树状大分子聚酰胺-氨PAMAM, 合成了1~3代树状大分子PAMAM-FCD, 用IR, 1H NMR和MALDI-TOF-MS等手段表征了化合物结构, 研究了Cu2+浓度对其荧光及紫外性能的影响. 结果表明, Cu2+可使其荧光强度和紫外吸收不同程度地增强. 在紫外光谱中, Cu2+自身的吸收峰消失, 表明Cu2+参与配位. PAMAM-FCD有望成为蓝光区荧光材料及树状大分子-铜杂化材料.

| Abstract: | Dendrimer of polyamidoamine PAMAM was modified with 2-fluorenecarboxaldehyde(FCD)to form dendrimers PAMAM-FCD of generation one,two and three,respectively. Structures and properties of PAMAM-FCD were characterized by IR,1H NMR and MALDI-TOF-MS,with special attention being paid to the effect of Cu2+ on the fluorescent and UV spectra of these dendrimers. The results show that,even though Cu2+ usually behaves as a fluorescence quencher,it can significantly enhance the fluorescence of these dendrimers. Furtherm... |
