The protein and MXene Ti3C2Tx were bonded by hydrogen bonds due to their abundant hydrogen bond donors and acceptors. The electrical characteristics of the composite biomaterial could be modified without changing the quantity of each component by varying the number of repeating amino acid sequence ...
The formation of intramolecular hydrogen bonds has a very pronounced effect on molecular structure and properties. We study both aspects in detail with the... B Kuhn,P Mohr,M Stahl - 《Journal of Medicinal Chemistry》 被引量: 345发表: 2010年 Molecular arrangements in sphingolipids. Conformation...
By mid-20th century, the weak conventional hydrogen bonds were reasonably well understood and widely accepted. Unlike covalent bonds, which vary in strength within a factor of ∼4 (30–120 kcal mol−1), hydrogen bonds are much less constrained in their geometry and physical properties, and ...
Hydrogen bonds and other intermolecular interactions in organometallic crystals Organometallic compounds have been studied with X-ray crystallography from their very discovery. Yet structural organometallic chemists were almost exclusi... GR Desiraju - 《Journal of the Chemical Society Dalton Transactions》 ...
However, alcohols, among the most common functionalities in organic chemistry5, have remained intractable because of their low affinity for late transition-metal catalysts6,7. Here we describe ligands that enable alcohol-directed arylation of δ-C(sp3)–H bonds. We use charge balance and a ...
Its unique ability to attract an exceptionally large number of hydrogen bonds induces the formation of a dense "hydrogen bond network" that has the potential to modify the properties of the surrounding molecules and their reactivities. The crucial role that water molecules play is described in this...
Unlike normal chemical bonds, hydrogen bonds (H-bonds) characteristically feature binding energies and contact distances that do not simply depend on the donor (D) and acceptor (:A) nature. Instead, their chemical context can lead to large variations even for a same donor−acceptor couple. As...
Then in 1869, as a result of an extensive correlation of the properties and the atomic weights of the elements, with special attention tovalency(that is, the number of single bonds the element can form), Mendeleev proposed the periodic law, by which “the elements arranged according to the ...
(bonding energy 5–30kJmol−1) than the typical hydrogen bonds (bonding energy ≈345kJmol−1), it has a prominent effect on the viscoelastic properties, phase separation, and the degree of crystallinity of the polymers. Single hydrogen bonds do not have the ability to induce the ...
