Pressure sensitive thin films of platinum porphyrin with a polymer binder are prepared by the micelle disruption method using redox-active surfactants with an azobenzene group. Much thinner films can be prepared by this method than conventional methods, which provide a quick time response to pressure changes. Furthermore, the thin films prepared by this method show a good linearity in the Stern-Volmer plot and a high sensitivity to pressure.
