Dark matter candidates with sub-GeV masses may create a visible signal in a liquid scintillator by scattering off of electrons in molecular orbitals. In particular, aromatic organic compounds such as benzene or xylene have small enough excitation energies that dark matter (DM) as light as a few MeV can create scintillation photons in the detector. In this talk we discuss how a kilogram-sized experiment with a small background event rate and a short exposure time can set strong constraints on the DM–electron cross section for DM masses of 2–100 MeV.
