| 摘 要： | 合成了外围由小分子2-芴醛修饰的树状大分子PAMAM(1G)-FCD, 用IR, 1H NMR, MALDI-TOF-MS等手段表征了其结构, 并对其荧光性能及Sn2+对该性能的影响进行了研究, 结果表明, Sn2+能使化合物荧光显著增强. 紫外光谱表明, 随着PAMAM(1G)-FCD溶液中Sn2+浓度的增加, 体系在360 nm处出现了新的吸收峰, 表明二者之间存在化学反应. 故该树状分子有望作为难得的蓝光区荧光材料及金属-树状大分子杂化材料. |
| 关 键 词： | 树状大分子PAMAM 2-芴醛 Sn2+离子 荧光性能 |

| Abstract: | A dendrimer of PAMAM(1G)-FCD was synthesized.Its structure was characterized via IR,1H NMR,MALDI-TOF-MS,etc.The fluorescent properties of PAMAM(1G)-FCD,as well as the influence of Sn2+ on this dendrimer,were also studied systematically.The results show that the fluorescence of this dendrimer can be significantly enhanced by Sn2+.The UV spectra detected a new absorption peak at 360 nm with the addition of Sn2+ into the solution of PAMAM(1G)-FCD,suggesting that chemical reaction occured in the Sn2+ and PAMAM(... |
| Keywords: | Dendrimer PAMAM 2-Fluorenecarboxaldehyde Sn2+ ion Fluorescent property |
