A one step, in situ, room temperature synthesis of yellow luminescent CdSe QDs was achieved in a metallohydrogel derived from a facially amphiphilic bile salt, resulting in a QD-gel hybrid. An ordered self-assembly and homogeneous distribution of the CdSe QDs in the hydrogel network was observed from optical and electron micrographs. The different excited state behavior of the CdSe QDs in the hybrid was revealed for the first time using time resolved spectroscopy. We also describe the successful isolation of the photoluminescent CdSe QDs from the gel followed by their re-dispersion in an organic solvent using suitable capping ligands.

金属水凝胶中发光CdSe量子点的原位形成：合成，分离，存储和再分散量子点的策略

在衍生自面部两亲性胆汁盐的金属水凝胶中完成了一步一步的黄色发光CdSe QD的原位室温合成，生成了QD-gel杂化物。从光学和电子显微照片观察到水凝胶网络中CdSe QD的有序自组装和均匀分布。使用时间分辨光谱法首次揭示了CdSe量子点在杂化体中的不同激发态行为。我们还描述了从凝胶中成功分离出光致发光CdSe QD，然后使用合适的封端配体将其重新分散在有机溶剂中的方法。
