Abstract:
We report intermolecular excimer formation by a common and popular polycyclic aromatic hydrocarbon pyrene at very low concentrations (low μM) when dissolved in deep eutectic solvents constituted of hydrated lanthanide salts and urea. Pyrene is not known to aggregate at such low concentrations in isotropic solvents and common liquids under similar conditions.
