## Description

- description: In this study, we employ a strategy to isolate and wrap a phosphorescent
    Pt(II)-porphyrin core with bulky yet flexible branched alkyl chains, resulting
    in a solvent-free liquid at room temperature that demonstrates excellent properties
    for sensing oxygen (O2) gas. Compared to reference material composed of Pt(II)-tetraphenylporphyrin
    and a highly gas-permeable polymer matrix, our Pt(II)-porphyrin liquid shows comparable
    sensitivity, better linearity, and greater photostability in its O2-responsive
    phosphorescence. This is attributed to the high homogeneity and gas solubility
    of the liquids, as well as to the shielding of luminescent-core units by bulky
    alkyl chains. The liquid nature of the materials allows for ratiometric sensing,
    where the compatibility of a phosphorescent Pt(II)-porphyrin liquid (O2-sensitive)
    and a fluorescent alkyl-pyrene liquid (O2-insensitive) enables reproducible monitoring
    of O2 concentration without specific calibration. Indeed, these results highlight
    the significant benefits of core-isolated luminescent liquids in diverse sensing
    applications.
