The tuning of the molecular material work‐function via strong coupling with vacuum electromagnetic fields is demonstrated. Kelvin probe microscopy extracts the surface potential (SP) changes of a photochromic molecular film on plasmonic hole arrays and inside Fabry‐Perot cavities. Modulating the optical cavity resonance or the photochromic film effectively tunes the work‐function, suggesting a new tool for tailoring material properties.
