“…As noted above, the growth of PbS NCs in the MEH‐PPV matrix was influenced by the steric effect of long MEH‐PPV chain as there was no charged functional groups on MEH‐PPV to tailor the NC growth 124. Interestingly, polyalkyloxythiophene−ZnO nanocomposites containing highly luminescent, homogeneous ZnO nanoparticles without the addition of capping agents were recently prepared by judiciously modifying polythiophene with alkyloxyl groups as side chains (i.e., alkyloxyl‐modified polythiophene) to facilitate the electronic affinity with Zn(OAc) 2 129. This new approach offered several advantages in terms of homogeneous size distribution, good dispersion, and distinctive band‐gap emission free from defect trapping 129.…”

Semiconductor organic−inorganic hybrid solar cells incorporating conjugated polymers (CPs) and nanocrystals (NCs) offer the potential to deliver efficient energy conversion with low‐cost fabrication. The CP‐based photovoltaic devices are complimented by an extensive set of advantageous characteristics from CPs and NCs, such as lightweight, flexibility, and solution‐processability of CPs, combined with high electron mobility and size‐dependent optical properties of NCs. Recent research has witnessed rapid advances in an emerging field of directly tethering CPs on the NC surface to yield an intimately contacted CP−NC nanocomposite possessing a well‐defined interface that markedly promotes the dispersion of NCs within the CP matrix, facilitates the photoinduced charge transfer between these two semiconductor components, and provides an effective platform for studying the interfacial charge separation and transport. In this Review, we aim to highlight the recent developments in CP−NC nanocomposite materials, critically examine the viable preparative strategies geared to craft intimate CP−NC nanocomposites and their photovoltaic performance in hybrid solar cells, and finally provide an outlook for future directions of this extraordinarily rich field.

“…[97][98][99][100] Side chain functionalization has been used to facilitate intimate mixing in composites. 32,[101][102][103] Conjugated polymer:polyelectrolyte complexes have also come a long way to improve polymer processing. [104][105][106] For example, poly(2-acrylamido-2-methyl-1-propanesulfonic acid) has been shown to both solubilize and stabilize PANI in complexes.…”

This review covers recent advances in conjugated polymers and their application in energy storage. Conjugated polymers are promising cost-effective, lightweight, and flexible electrode materials. The operating principles of conjugated polymers are presented within the framework of their potential for energy storage. Special focus is given to polyaniline electrodes. Recent advances are reviewed including new methods of synthesis, nanostructuring, and assembly. Also, covered are applications that take full advantage of the mechanical properties of conjugated polymers and future applications of these novel materials.

“…The inset image shows the emission spectra of bare ZnO NR exhibiting a UV emission peak at 384 nm (3.23 eV). The SAMs on ZnO NRs exhibited a photoluminescence (PL) emission peak at 389 nm (3.19 eV) with slight red shift confirming the surface functionalization[41]. After incorporation of the AuNPs, the UV emission peak blueshifted to 380 nm (3.26 eV) accompanied with quenching of the PL intensity for APhS and ACP (Figure 8 a&b) and very slight reduced intensity for ATP (Figure 8c).…”
