bondacceptorwhereas the hydrogen attached to a more electronegative atom serves as the hydrogen bonddonor. The proton acceptor is the electronegative atom that is not covalently bound to the hydrogen. The proton donor is the atom covalently bound to the hydrogen. The proton donor is aLewis base....
The formation of the DES is attributed to the H-bonding interaction(s) present between the salt and the HB donor. Consequently, addition of a predominantly HB donor or a predominantly HB acceptor cosolvent to such DESs may result in intriguing features and properties. We present investigation of...
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...

New heteroscorpionate ligands with hydrogen bond donor and acceptor groups: synthesis, characterization and reactivity with divalent Co, Zn and Ni ions 来自 国家科技图书文献中心 喜欢 0 阅读量: 19 作者:Z Shirin,CJ Carrano 摘要: Three new N 2O heteroscorpionate ligands designated L6OH, L7OH ...
A hydrogen bond is an intermolecular force that occurs between a hydrogen atom (donor) and an electronegative atom such as nitrogen, oxygen, or fluorine (acceptor). In many cases, hydrogen bond interactions are used in supramolecular interactions to obtain nanoscale assemblies. Natural polyphenols suc...
bonds (H-bonds) are a specific type of electrostatic interaction between a proton attached to an electronegative atom (such as N or O) and a lone pair of electrons on an electronegative atom such as N, O, or F. The former is called the H-bond donor, the latter the H-bond acceptor....
Indeed, the heterocyclic tetrazole group is a perfect potential hydrogen-bonding supramolecular synthon based on the fact that it contains both hydrogen-bond acceptor (N) and donor (NH) groups, and the 5-substitution can provide rich construction entities. On the other hand, when forming hydrogen...
Several multiterm linear solvation energy models which incorporate directly or indirectly hydrogen bond donor-acceptor parameters were compared experimentally. These included the Kamlet-Taft alpha(KT) scale, the Abraham alpha(2)H scale, and the acceptor (AN*) parameter of Riddle and Fowkes. An enlar...
Most noticeable feature of Table I is the predominance of the bonds of the donor-acceptor type which correspond to the shorter, stronger bonds and are part of the infinite chains or are the inner bonds of finite chains, a consequence of the ''cooperative effect'' which is also discussed. ...
