“…Then, DSC was used to confirm the existence of P3HT and PPI blocks, as shown in Figure (b). The DSC curve for P3HT homopolymers ( M n = 9.1 kDa) gave a T g at 84 °C and a single endothermic peak ( T m ) at 232 °C, respectively, which was consistent with the reference reports that P3HT with M n of ∼8.0 kDa showed a endothermic peak at 218–220 °C, and the higher endothermic temperature here was resulted from the larger molecular weight of P3HT. The PPI homopolymers ( M n = 78.6 kDa) showed a T g at 177 °C and a single endothermic peak at 311 °C.…”

In this article, the synthesis of a series of conjugated rod–rod block copolymers based on poly(3‐hexylthiophene) (P3HT) and poly(phenyl isocyanide) (PPI) building blocks in a single pot is presented. Ni‐catalyzed Grignard metathesis polymerization of 2,5‐dibromo‐3‐hexylthiophene and subsequent addition of 4‐isocyanobenzoyl‐2‐aminoisobutyric acid decyl ester in the presence of Ni(dppp)Cl2 as a single catalyst afford P3HT‐b‐PPI with tunable molecular weights and compositions. In solid state, microphase separation occurred as differential scanning calorimetric analysis of P3HT‐b‐PPI revealed two glass transition temperatures. In solutions, the copolymers can self‐assemble into spherical aggregates with P3HT core and PPI shell in tetrahydrofuran and exhibit amorphous state in CHCl3. However, atomic force microscopy revealed that the block copolymers self‐assemble into nanofibrils on the substrate. These unique features warrant the resultant conjugated rod–rod copolymers' potential study in organic photovoltaic and other electronic devices. © 2013 Wiley Periodicals, Inc. J. Polym.

“…225 In recent 5 years, various block copolymer compatibilizers were synthesized and used as the third component in OSCs.

Han et al 226 used an asymmetric rod-coil block copolymer P3HT-b-PTMSM in P3HT/PC 61 BM blend to form a passivation layer between the microscopically phase-separated D/A domains.…”

REVIEW This journal isOrganic solar cells (OSCs) with third component consisting of a donor material, an acceptor material and a third component (organic or inorganic, semiconductor or insulator) received increasing attention in recent five years and the power conversion efficiencies approached 10%. Compared with the traditional binary (two-component) blend, three-component OSCs presented some advantages: broader and stronger absorption, more efficient charge transfer, more efficient charge transport pathways, better charge extraction at electrodes and improved stability. Various types of third components, such as light-absorbing small molecules or polymers, fullerene or non-fullerene acceptors, metal-or carbon-based nano materials, quantum dots, and polymer or small molecule nonvolatile additives were used in OSCs. In this contribution, we review the recent developments in three-component OSCs using various third components. In particular, the absorption complementation, phase separation and nanostructure in three-component OSCs are addressed. Graphical contents entryThis review highlights the recent progress on the fabrication of organic solar cells with various third components which can improve the power conversion efficiency and stability.

“…). Introducing side alkyl substituents into poly(thiophene) molecules makes it possible to obtain the monomolecular solution without association of these polymers, thus increasing their adaptability to streamlined manufacturing and opening possibilities of studying molecular properties of poly(thiophene)s. Due to their low‐cost production and relatively easy processability, semiconducting poly(thiophene)s are used in organic solar batteries or field‐effect transistors …”

Conducting polymers demonstrate low solubility in organic solvents. Introducing aliphatic substituents into polymer chains improves their solubility, but may also lead to changes in conformational characteristics of macromolecules. In the present work, the studies of hydrodynamic properties and conformational characteristics of comb-shaped poly(3-hexylthiophene) with aliphatic side substituents were carried out in chloroform solutions. Conformational analysis of the studied macromolecules was performed for the first time using homologous series with a wide range of molecular weights of the polymers in dilute solutions. The hydrodynamic properties of these macromolecules were interpreted using the worm-like spherocylinder model and the straight spherocylinder model. The projection of the monomer unit in the direction of the main polymer chain k 5 0.37 nm was determined experimentally. The following parameters of poly(3-hexylthiophene) were characterized and quantified: equilibrium rigidity (Kuhn segment length) ff 5 6.7 nm and hydrodynamic diameter of a polymer chain d 5 0.6 nm.
