Regioregular poly(3-hexylthiophene) (P3HT) is one of the most studied hole conductors, which has proven to be instrumental in the continued development and understanding of conjugated polymers-based hybrid materials for organic electronics, especially in photovoltaics. The importance of P3HT as a standard building block is attributable to its outstanding characteristics such as its high environmental/thermal stability, electrical conductivity, and processability. The synthetic versatility of P3HT especially allows the preparation of multiple polymer topographies (homopolymers, random/block copolymers) as well as its functionalization with a high degree of control over the final structure and molecular weight. The availability of these robust synthetic methods offers not only the opportunity to tune the self-assembly, optical and electronic properties of P3HT-based conjugated polymers, but also those of the corresponding hybrid composite materials through interfacial engineering. This presentation describes some of our recent results concerning the side chain and endfunctionalization of P3HT and the impact of these polymers in fullerene- and metal oxide-based hybrid materials .
