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.

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(1G)-FCD system. This hybrid material of metal-dendrimer holds promise as a scarce material to emit blue fluorescence.

Key words: Dendrimer PAMAM, 2-Fluorenecarboxaldehyde, Sn2+ ion, Fluorescent property
