Unusually sensitive : A chiral sensor based on 1,1′‐bi‐2‐naphthol was prepared, which can provide visual enantioselective discrimination of α‐hydroxycarboxylic acids. When the sensor and the acid have matched configurations, an enantioselective precipitation occurs, which is accompanied by a dramatic (over 950‐fold) solid‐state fluorescence enhancement (see picture).
