Choline chloride-based ternary deep band gap systems

The structural features derived by the UV-VIS spectroscopical analysis of five ternary eutectic systems containing choline chloride as Hydrogen Bond Acceptor (HBA), and ethylene glycol and a second Hydrogen Bond Donor (HBD, water, glycerol, methanol, ethanol, and 2-propanol), have been determined and described in terms of band gap and Urbach energies (BGE and UE). In particular, the relationship between the molar composition of the ternary...
