Layer‐by‐layer assembly is used to produce thin films of J‐aggregates of cyanine dye molecules with an absorption constant of 10 6 cm –1 . The films display high reflection and absorption at resonance (see Figure, ∼50 nm films) and nanoscale features that make them well suited for use in strong‐coupling optoelectronic applications, enabling the creation of exciton–polariton optoelectronic devices that operate at room temperature.
