Nanostructured hybrid materials composed of functional block copolymers (BCPs) and inorganic nanoparticles (NPs) have attracted growing interest. In this paper, quantum dot/block copolymer (QD/BCP) hybrid assemblies with precise control of dispersion and localization of QDs into/on the thermo-responsive BCP micelles were constructed by the coordination effect. A series of BCPs with a poly(N-isopropylacrylamide) (PNIPAm) block and a polystyrene (PSt) block was synthesized by RAFT polymerization, and a monomer unit containing an 8-hydroxyquinoline (HQ) group with strong coordination interaction with QDs was introduced into the hydrophobic PSt blocks, hydrophilic PNIPAm blocks and the interface of the hydrophilic and hydrophobic blocks. The QD/BCP assemblies were built through locating the QDs in the core (CDMs), shell (SDMs) and the interface (IDMs) between the core and the shell in the BCP micelles via a coordination-driven assembly process. The resulting hybrid assemblies possess special dual-emitting properties in the case of introducing only one emitting element (QDs). The dual-emission comes from the inherent emissions of the QDs (red-emission) and the HQ–Zn complex (green-emission) on the surface of the QDs. The optical properties of the QD/BCP hybrid assemblies have the characteristics of temperature response. The SDM hybrid assembly can be applied to the selective detection of 2,4,6-trinitrophenol (TNP) and Hg²⁺ ions.

两亲热响应嵌段共聚物胶束中量子点的配位诱导组装：形貌，光学性质和应用†

由功能嵌段共聚物（BCP）和无机纳米粒子（NP）组成的纳米结构杂化材料引起了越来越多的兴趣。本文通过配位效应构建了量子点/嵌段共聚物（QD / BCP）杂化组件，可精确控制量子点在热响应性BCP胶束中的分散和定位。一系列具有poly（N通过RAFT聚合合成（异丙基丙烯酰胺）（PNIPAm）嵌段和聚苯乙烯（PSt）嵌段，并将包含与QDs具有强配位相互作用的8-羟基喹啉（HQ）基团的单体单元引入疏水性PSt嵌段，亲水性PNIPAm嵌段中以及亲水性和疏水性嵌段的界面。的QD / BCP组件是通过在芯和在BCP胶束壳之间的芯（存款机），外壳（SDMS）及接口商（IDM）定位所述量子点建经由协调驱动的组装过程。在仅引入一个发射元件（QD）的情况下，所得混合组件具有特殊的双发射特性。双重排放来自量子点表面的固有量子点（红色发射）和HQ-Zn络合物的固有发射（绿色发射）。QD / BCP混合组件的光学特性具有温度响应的特性。SDM混合组件可应用于2,4,6-三硝基苯酚（TNP）和Hg ²⁺离子的选择性检测。
