Establishing Predictive Models for Solvatochromic Parameters of Ionic Liquids
Venkatraman, Vishwesh; Kallidanthiyil Chellappan, Lethesh (Journal article; Peer reviewed, 2019)The use of ionic liquids (ILs) in applications ranging from catalysis to reaction media in organic synthesis has been successfully demonstrated in several cases. For any given IL application, fundamental properties, such ... -
Hydroxyl Functionalized Pyridinium Ionic Liquids: Experimental and Theoretical Study on Physicochemical and Electrochemical Properties
Kallidanthiyil Chellappan, Lethesh; Venkatraman, Vishwesh; Fiksdahl, Anne; Evjen, Sigvart (Journal article; Peer reviewed, 2019)Structurally modified hydroxyl functionalized pyridinium ionic liquids (ILs), liquid at room temperature, were synthesized and characterized. Alkylated N-(2-hydroxyethyl)-pyridinium ILs were prepared from alkylpyridines ... -
