Triplet solvation dynamics in supercooled hydrogen bonding liquids in hard and soft confinements

Overview

Many liquids show a dramatic change in their molecular dynamics when subject to a confining environment. The effects of the confinement on a liquid range from a suppression of crystallization below a certain pore size to an upshift or downshift of the glass transition of supercooled liquids within the pores. However, it is very difficult to investigate surface, density and finite-size effects separately with classic spectroscopic techniques, which measure the spatially averaged dynamics in a macroscopic sample. With the method of triplet solvation dynamics it is possible to locally access the relaxation dynamics within a macroscopic sample.
