Description
Xiaoyun Wu and five colleagues review how re-engineering the flanking groups around diketopyrrolopyrrole, a workhorse pigment-turned-semiconductor, unlocks functions far beyond its classic roles in transistors and solar cells. Standard synthesis fixes aromatic rings on both sides of the core, and those rings dictate energy levels, packing, and charge flow. Decades of swapping them delivered steady gains but boxed in the possible shapes.
Newer work breaks the mould with naphthalene motifs, vinyl links, and fused backbones that reshape how molecules couple and stack. Those moves stretch the material family toward flexible electronics, intelligent skins, and biological sensors that demand softness and responsiveness classic designs lack. The review organises the field into a structure-property-application map, presenting flanking-group design as the unifying lever for next-generation multifunctional organic electronics.
