On page 7436, B. V. Lotsch and co‐workers report the fabrication of antimony phosphate nanosheet‐based thin‐film devices. While a resistive thin‐film device can detect trace amounts of water, a photonic HSbP 2 O 8 /TiO 2 multilayer structure is effective at optically distinguishing between chemically similar solvent vapors through an intercalative sensing mechanism based on analyte‐specific host–guest interactions.
