The rapidly progressing field of organic electronics research has inspired a renaissance in the chemistry of dye molecules, compelling scientists to revitalize historical pigments, transform them into soluble dyes, and apply them in the construction of advanced macro(molecular) semiconducting materials. The Highlight by M. J. Robb et al. on page 1263 explores the resurgence of notable building blocks including diketopyrrolopyrrole (DPP), (iso)indigo, benzodipyrrolidone, and benzodifuranone, as well as the non-fullerene acceptor structures 9,9'-bifluorenylidene (99BF) and quinacridone shown here. Their outstanding characteristics and synthetic availability have led to cutting-edge materials with remarkable properties well-suited for organic electronic devices.
