Polydiacetylene‐based chemosensors are prepared by assembling liposomes of diacetylene monomers with terminal amine groups on an aldehyde‐modified glass substrate, and polymerizing them by irradiation with UV light. Incubation of the immobilized film sensor in a poly(acrylic acid) solution results in a color change from the original blue (solid line in Figure) to the red phase (broken line).
