Hydrogen Bonding in Self-Healing Elastomers
In the past decade, the self-healing elastomers based on multiple hydrogen bonding have attracted ample attention due to their rich chemical structures, adjustable mechanical properties, fast healing speed, and high healing efficiency. Through prolonging

Asymmetric nucleophilic fluorination under hydrogen bonding phase-transfer catalysis
H-bond to deliver fluoride Simple fluoride salts are theoretically convenient reagents for carbon-fluorine bond formation. In practice, they are often insoluble in the solvents that dissolve their reaction partners. Pupo et al.

In spite of the key role of hydrogen bonding in the structural stabilization of the prototypic hybrid halide perovskite, CH3NH3PbI3 (MAPbI3), little progress has been made in our in-depth understanding of the hydrogen-bonding interaction between the MA ...

Preferred Hydrogen-Bonding Partners of Cysteine: Implications for Regulating Cys Functions.
The hydrogen-bonding interactions of cysteine, which can serve as a hydrogen-bond donor and/or acceptor, play a central role in cysteine's diverse functional roles in proteins.

O–H hydrogen bonding promotes H-atom transfer from α C–H bonds for C-alkylation of alcohols
A trio helps activate C-H bonds in alcohols Enzymes can accelerate chemical reactions by activating specific portions of a molecule through well-placed H bonds. Jeffrey et al. showcase the power of H-bonding in a synthetic context.

Tetraalkylammonium Salts as Hydrogen-Bonding Catalysts.
Although the hydrogen-bonding ability of the α hydrogen atoms on tetraalkylammonium salts is often discussed with respect to phase-transfer catalysts, catalysis that utilizes the hydrogen-bond-donor properties of tetraalkylammonium salts remains unknown.

Reversible polymers formed from self-complementary monomers using quadruple hydrogen bonding.
Units of 2-ureido-4-pyrimidone that dimerize strongly in a self-complementary array of four cooperative hydrogen bonds were used as the associating end group in reversible self-assembling polymer systems.

Adhesion and Surface Interactions of a Self‐Healing Polymer with Multiple Hydrogen‐Bonding Groups
The surface properties and self‐adhesion mechanism of self‐healing poly(butyl acrylate) (PBA) copolymers containing comonomers with 2‐ureido‐4[1H]‐pyrimidinone quadruple hydrogen bonding groups (UPy) are investigated using a surface forces apparatus (SFA)
