The possibility of the fabrication of Langmuir–Blodgett polyamic acid-based dye-containing pH-indicative films is demonstrated. The lipoidal dyes, n-decyl fluorescein and n-decyleosin immobilized in a polymeric multilayer nanosized structure, exhibit changes in absorption and emission within a pH range from 1 to 10, which can be used in sensor devices.
