There is an increasing importance of micro/nano scale flows for the development of MEMS/NEMS (Micro/Nano Electro-Mechanical Systems). The pressure sensitive paint (PSP) technique is considered to be suitable for analyses of these flows in principle. We, therefore, have developed pressure sensitive molecular film(PSMF) based on the Langmuir-Blodgett(LB) technique, which is a method to make high ordered mono-molecular films, to overcome problems of the existing PSP at micro/nano systems. In this study, we adopt two luminophores for the PSMF in order to select the one for low pressure range and the other for near-atmospheric pressure depending on the pressure range of interest. We clarify their fundamental properties such as pressure sensitivity. As a result, it is confirmed that the PSMF with Palladium(II) MesoporphyrinIX (PtMP) is effective in the low pressure range and that with Platinum(II) MesoporphyrinIX (PdMP) is effective in the atmospheric pressure range.
