Abstract:
Supramolecular colorimetric pressure sensing in solution was achieved using silicon-bridged diazulenylmethyl cation 1PF6, whose monomer-dimer equilibrium shifts under hydrostatic pressure. Pressurization promotes desolvation of the strongly solvated dimer to produce the monomer. The resulting pressure-induced equilibrium shift enables colorimetric sensing for quantitative pressure readout.
