Abstract

Time resolved phosphorescence spectroscopy of molecular probes in organic supercooled liquids indicates solvation dynamics active on the ms-s time scale. A detained analysis of the positive solvato-chromism of quinoxaline allows for experimentally quantifying the change in dipole moment upon T10 excitation and the polarity of supercooled liquids. Solvation in macroscopically unpolar solvents indicates the important role of microscopic polarity for rationalizing the local dielectric responses governing the solvation dynamics.
