Supramolecular colorimetric pressure sensing: ratiometric quantification based on pressure-modulated association

Key Points

• This research focuses on utilizing supramolecular systems for pressure sensing.
• Developed a pressure-sensing method based on colorimetric responses.
• Utilized silicon-bridged diazulenylmethyl cation 1PF₆.
• Investigated the monomer-dimer equilibrium under hydrostatic pressure.
• Hydrostatic pressure shifts the monomer-dimer equilibrium.
• Pressure results in desolvation of the dimer, enhancing sensing capabilities.
