Well-defined polymer/inorganic nanoparticle (NP) hybrids are of vital importance to the development of nanomaterials with desired optical, electric, magnetic, and many other properties. We demonstrate the efficient incorporation of n-trioctylphosphine oxide (TOPO)-coated CdSe quantum dots (QDs) into polystyrene-b-polyacrylic acid (PS-b-PAA) colloids by a “solution phase self-assembly”approach. Driven by the hydrophobic interactions, the CdSe QDs are homogeneously encapsulated in the hybrid colloids. The sizes of the hybrid colloids with different structures, i.e., simple spherical ...
