“…AFM measurement of the thin film based on P3HT-b-PEO/PCBM revealed that the introduction of PEO segment contributed to generate ordered lamellar morphology with the smaller size compared with the P3HT/PCBM blend. 133 The block copolymer P40 reported by Chen showed phase segregation on the devices. 134 During polymer deposition by spin-coating, the fluorinated block segregated on the surface of P3HT.…”

Semiconducting polymers have been developed during the last few decades and are currently used in various organic electronics applications. Regioregular poly(3-hexylthiophene) (P3HT) is the most employed semiconducting polymer for organic electronics applications. The development of living Grignard metathesis polymerization (GRIM) allowed the synthesis of P3HT with well-defined molecular weights and functional end groups. A large number of block copolymers containing P3HT have been reported, and their opto-electronic properties have been investigated. The performance of P3HT homopolymer and block copolymers in field-effect transistors and bulk heterojunction solar cells are discussed in this review. The morphology of the P3HT materials is also discussed.

In hybrid photovoltaics, an organic and an inorganic semiconductor are combined in the active layer, with the advantages of both material classes in a single device. The organic component contributes towards the possibility for wet chemical device preparation with potentially low costs in combination with achieving flexible devices. From the inorganic component an increase in stability, as well as superior opto‐electronic properties, is added. Given the large diversity of organic and inorganic semiconductors, a large number of possible realizations of hybrid solar cells emerge. In the present review, we limit to hybrid solar cells which combine conjugated polymers with inorganic materials such as titanium dioxide, zinc oxide, silicon, germanium and quantum dots to keep focused. Particular emphasis is put on different routes to tailor nanostructures, such as the use of semiconductor block copolymers. The inorganic component is either synthesized directly in one of the blocks or added as a pre‐synthesized nanomaterial to form the hybrid material. Alternatively, the block copolymer is used as a structure‐directing template in a sol–gel synthesis approach to have tailored inorganic nanostructures, which are back‐filled with the organic component to fabricate the hybrid material. Hybrid solar cells based on crystalline Si are discussed for comparison.

“…In order to create the linkage between P3AT and anionically‐prepared polymer segments, Tsuchiya, Ogino, and coworkers utilized the Suzuki‐Miyaura coupling reaction. As shown in Scheme , α‐bromo‐chain‐end‐functional P3HT was coupled by ω‐boronic‐ester‐chain‐end‐functional PEO, resulting in the formation of an arylene‐type CC bond to synthesize P3HT‐ b ‐PEO . Very recently, the same group reported the synthesis of P3HT‐ b ‐PDMS by an addition reaction based on hydrosilation using a platinum catalyst (Scheme ) .…”

In this Talent article, the synthesis of well‐defined block and miktoarm star‐branched polymers is described by the combination of living anionic polymerization (LAP) and Kumada catalyst‐transfer polymerization (KCTP), mostly focusing on poly(3‐alkylthiophene) (P3AT)‐based block copolymers and miktoarm star‐branched polymers. The two synthetic methodologies are introduced as follows: (a) a chain‐extension method using chain‐end‐functional polymers via site transformation reaction, and (b) a linking reaction method between two polymer building blocks. The most promising method (b) can further be divided into four different approaches, (b‐1) direct addition reaction of living anionic polymers with chain‐end‐functional P3HT; (b‐2) “Click” reaction between two chain‐end‐functional polymers; (b‐3) direct coupling reaction of living anionic polymers with chain‐end‐functional P3HT; and (b‐4) ionic bond formation of chain‐end‐functional polymers. Based on the recent progresses in synthetic methodologies, versatile block copolymers and miktoarm star‐branched polymers have been successfully produced, well controlling the molecular weights (MW) and dispersities (ÐM).
