(2-methoxyethoxy)-10 H -dipyrrin-1-one, with solubilizing 2-methoxyethoxy β-substituents on the lactam ring and two hexanoic acid groups (one at C(9), the other at C(8) of the pyrrole ring) was synthesized to determine its ability to form intramolecular hydrogen bonds to the lactam ...
class of H-bond, the doubly ionic H-bond, found predominantly in ILs is introduced. QC calculations are a key route to understanding the H-bonds that form within ILs, and the importance of QC calculations in providing a benchmark for a “pure” H-bond free of external influences is ...
