The main intermolecular interactions are the π–π between the pyridine and the fluorinated ring of molecules stacking in columns (1a with 1a and 1b with 1b) and the O–HN H-bonds. The imine acts as a H-bond-d
However, a significant amount of bonding stability can be achieved when there is formation of multiple hydrogen bonds between two such systems and elicits a response. Because of the presence of amino acid residues in receptors containing both the hydrogen bond donor and acceptor functionalities, ...

Weak though this noncovalent bond is, it's extremely sensitive to hydrogen bond donor and acceptor, which makes the switchable performance of the membrane unpreceden- tedly convenient compared with reports in previous literatures20,21,29, just by using water and ethanol alternately. It has shown ...

和电负性极强的原子比如氧、氮、氟相连的氢原子可以作为氢键供体,也就是分子中的N-H和O-H。电负性极强的原子比如氧、氮、氟自己是氢键受体。 氢键供体Hydrogen-bond donors被认为比氢键受体hydrogen-bond acceptors给药物设计者带来更多问题。类药物化合物的大部分极性来自于氢键受体,因为它们的数量通常超过了氢键供体...
Is a hydrogen bond a true chemical bond? What kind of molecule can experience hydrogen bonding? What is the electronegativity of hydrogen? What is a hydrogen bond donor? What is a covalent bond in chemistry? Are hydrogen bonds covalent?
A hydrogen bond is mainly formed between a donor atoms such as an amine, which acts as a ligand, or a lewis base and acceptor atom like carboxylic acid. The larger the number of amino acids in a given protein molecule, the greater is the probability of the formation of hydrogen bonds. ...
Role of ionic liquids and their future alternative toward protein chemistry 16.15 Role of deep eutectic solvents on protein chemistry DESs comprise combinations of a hydrogen donor and a hydrogen acceptor. The literature available explained that the ILs can be hydrogen acceptors and have the capacity ...
