Important interfacial processes in disciplines ranging from medicine to the separations sciences occur over a wide range of pressures, temperatures, and time scales. In this paper we report new high-pressure total internal reflection fluorescence (HP-TIRF) apparatus that allows rapid measurements sub-monolayers contact with liquids supercritical fluids between 293 K 353 up 250 bar picosecond resolution. We use HP-TIRF system study in-plane rotational reorientation dynamics fluorescent probe...
We report on the rotational reorientation dynamics of a fluorescent reporter molecule, BODIPY 494/503, within n-alkyl (n = 1–18) monolayers formed quartz in contact with pure supercritical carbon dioxide (scCO2) at 313 K (reduced temperature, Tr 1.03) between reduced CO2 density (ρr ρexp/ρc) 0 and 1.8. The 494/504 are described by free ≥ 4) hindered rotor ≤ 6) models. As increases, rotation shifts toward rotation, local viscosity cybotactic region surrounding monolayer decreases. These...
