    The paper presents luminescence properties of platinum porphyrins embedded in ultrathin polymer Langmuir-Blodgett (LB) films (nanosheets). We prepared amphiphilic copolymer of platinum porphyrin with N-dodecylacrylamide (p(DDA/PtTPP)). The copolymer p(DDA/PtTPP) with 6mol% PtTPP content took a stable monolayer formation at the air-water interface. Luminescent p(DDA/PtTPP) nanosheets were successfully assembled on solid substrates by the vertical dipping method. The luminescence intensity as a function of the number of layers revealed that platinum-porphyrin is effectively quenched by molecular oxygen for multilayered p(DDA/PtTPP) nanosheets with more than ten layers. Atomic force microscopy revealed that the p(DDA/PtTPP) nanosheets had relatively rough surfaces, leading to high surface-tovolume ratio. The oxygen sensitive polymer nanosheet multilayers enables us to monitor dissolved oxygen concentration in water.
