Luminescent oxygen-sensory polymer-coatings composed of platinum tetrakis(pentafluorophenyl)-porpholactone (PtPL) and -porphyrin (PtPP) with poly(trimethylsilylpropyne) (PMSP) were prepared for visualization of the oxygen partial pressure on two parallel planes or a biplanar surface. PMSP formed a smooth and tough coating as a high oxygen-permeable polymer matrix with a thickness of ca. 2 μm, which homogeneously contained the luminescent dye probe, PtPL or PtPP. Under UV light (395 nm) irradiation, the coatings displayed strong magenta and red luminescence with maximum peaks at 750 and 650 nm ascribed to the PtPL and PtPP, respectively. The luminescence of the two coatings was efficiently quenched by oxygen which allowed the development of engineering curve to analyze the oxygen partial pressure. The luminescence intensities of the two coatings were separately monitored in order to allow the simultaneous measurement of the oxygen partial pressure distribution upon two planar surfaces.
