Chiral polymer-dispersed liquid crystals can enhance the emission of organic luminophores introduced into the composition. Such optical materials are useful for creating panoramic optical film for pressure and temperature sensors. The optical properties of chiral polymer-dispersed crystals, doped with platinum porphyrin complex, were experimentally investigated. The dependence of the luminophore emission on the pressure and temperature was measured. •We studied the films based on polymer-dispersed chiral LC with organic luminophore.•The effect of chiral LC on the luminescence intensity through quenching by oxygen was studied.•The dependence of the luminophore emission on the pressure and temperature was measured.•We showed the film sensitivity to a pressure variation to be increased by up to 4–5 times.•We showed such films can be used for the sensor of temperature and pressure simultaneously.
