An approach toward intercalant tunable nanosheet‐based Fabry–Pérot sensors is presented. The intercalant tetrabutylammonium significantly increases the sensitivity of the photonic nose sensor to volatile organic compounds with increasing polarity, enabling polarity‐driven color‐coded vapor differentiation. Paired with the improved millisecond response times for polar vapors, vapor imaging with spatio‐temporal resolution is within reach.
