Regioregularity-control of conjugated polymers: from synthesis and properties, to photovoltaic device applications

Abstract: In the last decade, extensive academic and industrial efforts have been devoted to developing efficient conjugated polymers (CPs) for organic electronics. Specifically, the relationship between the molecular structures, properties, and...

“…196,214,215 It should be noted that a reduction in P3AT regioregularity shortens persistence lengths, reduces crystallization and interchain interactions, and can therefore transition such rod-coil BCP to coil-coil types. 216,217 Nevertheless, polychalcogenophene crystallization occurs readily at low temperatures, providing competition for other self-assembly pathways. 196,218 In fact, P3AT crystals can extend past their confined phases, and because this phenomenon, termed breakout crystallization, heightens disorder, derived devices suffer from diminished optoelectronic properties.…”

“…RR is a parameter that also determines the balance between the crystalline and amorphous characteristics of polymer films as it affects the packing density of polymer chains. [ 99 ] Therefore, it is expected to have important consequences on the electrical and mechanical properties of thin films.…”

“…High regioregularity (RR) conjugated polymers exhibit good optical and electrical properties but often induce but poor mechanical resilience, and vice versa for the low RR materials. [ 79 ] Therefore, precise RR control is important in the design of conjugated polymers for mechanically robust active layer. Both electrical and mechanical properties can be optimized simultaneously by blending photoactive materials with high and low RR or combining high RR and low RR blocks in one polymer chain.…”
