N2 - Pressure‐Sensitive Paint (PSP) is a powerful measurement technique to obtain pressure distribution on a model of interest by measuring the emission intensity of the PSP coating with a camera. Since a PSP coating is prepared by applying a solution containing an organic solvent, gen-erally, by sprayer, the properties such as the pressure‐ and the temperature‐sensitivity depends on the skill of the person applying it. This fabrication process is one of the barriers to use of the PSP technique because of the legal restrictions on the use of organic solvents. Thus, a sticker‐like PSP coating is useful because it does not require the use of organic solvent and the applying skill. In this study, we have fabricated freestanding Pressure‐Sensitive Nano‐Sheet (PSNS) by a sacrificial layer process using a spin‐coating method. We employed Pt(II) meso‐tetra(pentafluorophenyl)porphine (PtTFPP) as a pressure‐sensitive dye and poly(1‐trimethylsilyl‐propyne) (PTMSP) and poly(L‐lactic acid) (PLLA) as a polymer binder; thus, the PSNS samples based on PTMSP and PLLA were pre-pared. The pressure‐ and the temperature‐sensitivity, the lifetime of the luminescence, and the quantum yield of the fabricated PSNS have been investigated. The pressure‐sensitivity of PTMSP-based PSNS is higher than that of PLLA‐based PSNS. Conversely, the quantum yield of PLLA‐based PSNS is higher than that of PTMSP‐based PSNS.
