Synthesis and photophysical property of well-defined donor–acceptor diblock copolymer based on regioregular poly(3-hexylthiophene) and fullerene

Block Copolymer Nanostructures for Technology

“…A small photovoltaic effect under monochromatic illumination was demonstrated [77]. Similar work using a poly(3-hexylthiophene) (P3HT) donor block and C 60 -grafted PMMA [78] shows improved photoluminescence quenching compared to a simple blend of P3HT and phenyl-C 61 -butyric acid methyl ester (PCBM), indicating better exciton dissociation, although photovoltaic cells made from such material demonstrated only a modest photovoltaic effect. Recent work by Tao et al [79] using P3HT as the donor and perylene as the acceptor, and by King et al [80] using PvTPA-perylene, also demonstrate phase separation of the blocks, although the PV effect is decidedly modest in both cases.…”

Kumada chain-growth polycondensation as a universal method for synthesis of well-defined conjugated polymers

“…Various P3HT-based rod-coil block copolymers with functional coil segments ( Figure 16) were synthesized and systematically investigated inspired by the construction of the films comprising well-defined donor-acceptor nanostructures for bulk heterojunction PSCs [85][86][87][88]. The devices of PDA-3 exhibited a power conversion efficiency (PCE) of 0.49% upon annealing at 150 °C for 20 min.…”

Polystyrene‐Based C60 Acceptor Copolymers through Azide–Alkyne Click Chemistry Approaches

“…Some groups already proved a positive effect of block copolymers in this regard. Jo and co-workers [ 16 ] synthesized a diblock copolymer with P3HT and a fullerene-containing methacrylate block. They showed that the photoluminescence quenching for P3HT/PCBM blends containing a few percent of this block copolymer as surfactant was much better than for the pure blend, indicating a more effi cient charge transfer.…”
