我们报告了一锅合成,封装,和高品质的量子点的基础上使用的两亲性和多齿聚合物配体的增溶。在这种“一体化”程序中,所得QD首先被多齿配体封端,然后在暴露于水时被相同多齿聚合物的第二层自发地包封和溶解。除了提供更好地控制量子点成核和生长动力学(包括对奥斯特瓦尔德熟化的抗性)之外,该过程允许在量子点核上原位生长无机钝化壳,使得能够一锅法合成具有从可见光到近红外波长的可调谐光发射的I型和II型核-壳QD。
We report one-pot synthesis, encapsulation, and solubilization of high-quality quantum dots based on the use of amphiphilic and multidentate polymer ligands. In this “all-in-one” procedure, the resulting QDs are first capped by the multidentate ligand, and are then spontaneously encapsulated and solubilized by a second layer of the same multidentate polymer upon exposure to water. In addition to providing better control of nanocrystal nucleation and growth kinetics (including resistance to Ostwald ripening), this procedure allows for in-situ growth of an inorganic passivating shell on the nanocrystal core, enabling one-pot synthesis of both type-I and type-II core-shell QDs with tunable light emission from visible to near-infrared wavelengths.
