Zusammenfassung:•Sensors (film-shaped polymers) change their colour in presence of phenols.•The sensory materials are polymers with chemically anchored sensory motifs.•Sensors allow onepod determination of total phenolic content & antioxidant activity.•Proof of concept: 8 honeys were measured with the proposed sensors and a smartphone. We have developed a new method for the rapid (2 h) and inexpensive (materials cost
