Summary:Illuminating! Isolation of a π‐core by covalently attached flexible hydrocarbon chains has been employed to synthesize blue‐emitting oligo(p‐phenylenevinylene) (OPV) liquids with tunable viscosity and optical properties. A solvent‐free, stable, white‐light emitting ink/paint, which can be applied onto various surfaces and even onto LEDs, was made by blending of liquid OPVs with emissive solid dopants.
