Abstract

We have demonstrated a polymer mediated "bricks and mortar" method for the self-assembly of quantum dots (QDs). This strategy allows QDs to self-assemble into structured aggregates using complementary three-point hydrogen bonding. The resulting nanocomposites have distinct morphologies and inter-particle distances based on the ratio between QDs and polymer. Time resolved photoluminescence measurements showed that the optical properties of the QDs were retained after self-assembly.

摘要

我们展示了一种聚合物介导的量子点（QDs）自组装“砖石结构”方法。该策略允许量子点利用互补的三点氢键自组装成结构化聚集体。基于量子点与聚合物之间的比例，所得纳米复合材料具有独特的形态和颗粒间距离。时间分辨光致发光测量表明，自组装后量子点的光学性质得以保留。
