“…S11 e S16 in supporting information). The field-effect mobilities reported for various P3HT block copolymers vary in the range from 10 À2 to 10 À5 cm 2 V À1 s À1 [34,35,46,47]. However, relatively high hole mobilities were observed for P2 to P4 copolymers even at a low content of semiconducting P3HT block (25.9e50.5 mol-% P3HT).…”

“…On the basis of the excellent properties of polymer such as optical transparency, physical and chemical stability, tunable mechanical properties, and easy molding, incorporation of QDs into polymer matrix is an efficient method to enhance the functions of QDs. Studies on QD–polymer composites are popular in recent years to incorporate the inorganic and organic properties 21–32. Various methods to prepare polymeric nanocomposites have been explored such as direct surface modification of QDs with various polymers, embedding QDs in polymer colloids, layer‐by‐layer assembly, and so forth 1…”

A series of positively charged imidazolium-functionalized ionic polyurethanes (IPUs) were prepared in one-step polymerization process by polymerization of presynthesized short-chain imidazolium-based ionic diol, polyethylene glycols with different molecular weights as long-chain diols, and toluylene-2,4-diisocyanate. The structures of IPUs are confirmed by 1 H NMR analysis, and the thermogravimetric analysis measurement indicates that the IPUs have high degradation temperature. Fluorescent nanocrystal-polymer composites CdTe-IPU can be prepared conveniently, by the electrostatic interaction between positively charged IPUs and the negatively charged aqueous CdTe quantum dots (QDs). UV-vis absorption and photoluminescence spectra indicate the photochemical stability and strong fluorescent emission of CdTe-IPU composites. The quantum yields (QYs) of the composites are high and basically restore the QYs of the pure QDs. In addition, the transmission electron microscopy photographs show that the QDs in composites are uniform (about 3 nm in diameter) and monodisperse. The obtained nanocomposites are powder or elastomers with good film building. The casted CdTe-IPU films are transparent under visible light, and the colors of the composites and their films are vivid under a UV lamp. V C 2011 Wiley Periodicals, Inc.

“…In 2011, Palaniappan et al synthesized a poly(3‐hexylthiophene)‐ b ‐poly(4‐vinylpyridine) diblock copolymer via a combination of GRIM and RAFT polymerization ( P3 ). Comparing the block copolymer with the initial P3HT precursor they observed improved dispersibility of the CdSe QDs in the block copolymers, as shown in TMAFM (tapping mode atomic force microscopy) images …”

Simple blends of inorganic nanocrystals and organic (semiconducting) polymers usually lead to macroscopic segregation. Thus, such blends typically exhibit inferior properties than expected. To overcome the problem of segregation, polymer coated nanocrystals (nanocomposites) have been developed. Such nanocomposites are highly miscible within the polymer matrix. In this Review, a summary of synthetic approaches to achieve stable nanocomposites in a semiconducting polymer matrix is presented. Furthermore, a theoretical background as well as an overview concerning morphology control of inorganic NCs in polymer matrices are provided. In addition, the morphologic behavior of highly anisotropic nanoparticles (i.e. liquid crystalline phase formation of nanorod-composites) and branched nanoparticles (spatial orientation of tetrapods) is described. Finally, the morphology requirements for the application of inorganic/organic hybrid systems in light emitting diodes and solar cells are discussed, and potential solutions to achieve the required morphologies are provided.
