Abstract

利用2-溴代异丁酸乙酯(NA)做为引发剂,通过原子转移自由基聚合(ATRP)合成聚甲基丙烯酸环氧丙酯(PGMA).乙二胺(EDA)对PGMA的环氧基团进行开环反应制备具有亲水性质的梳状聚合物PGMA-g-EDA.用核磁共振(1H-NMR),红外光谱(FTIR)及凝胶渗透色谱(GPC)表征了PGMA和PGMA-g-EDA的结构和分子量分布.PGMA-g-EDA聚合物对量子点进行修饰,通过配体交换,制备水溶性的量子点(PGMA-g-EDA-QDs).通过紫外-可见光谱(UV-Vis)及荧光发射光谱(PL)对该量子点进行光学性质的研究,结果表明量子点的结构未被破坏,保持了原量子点的光学性质.用透射电镜(TEM)及动态光散色(DLS)表征,结果表明得到的水溶性量子点尺寸小,分布均匀,无团聚.通过研究量子点对光氧化,化学氧化,耐酸性的研究表明该方法得到的水溶性量子点具有很好的稳定性,并且聚合物的合成和量子点的修饰方法方便简单.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
