Breaking a dative bond with mechanical forces [PDF]
Nature Communications, 2021 Abstract Bond breaking and forming are essential components of chemical reactions. Recently, the structure and formation of covalent bonds in single molecules have been studied by non-contact atomic force microscopy (AFM). Here, we report the details of a single dative bond breaking process using non-contact AFM.

Mechanostereochemistry and the mechanical bond [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 The chemistry of mechanically interlocked molecules (MIMs), in which two or more covalently linked components are held together by mechanical bonds , has led to the coining of the term mechanostereochemistry to describe a new field of chemistry that embraces many aspects of MIMs, including ...

Mechanically bonded macromolecules [PDF]
Chem. Soc. Rev., 2010 Mechanically bonded macromolecules constitute a class of challenging synthetic targets in polymer science. The controllable intramolecular motions of mechanical bonds, in combination with the processability and useful physical and mechanical properties of macromolecules, ultimately ensure their potential for applications in materials science ...

Anion–π Catalysis Enabled by the Mechanical Bond** [PDF]
Angewandte Chemie International Edition, 2021 Abstract We report a series of rotaxane‐based anion–π catalysts in which the mechanical bond between a bipyridine macrocycle and an axle containing an NDI unit is intrinsic to the activity observed, including a [3]rotaxane that catalyses an otherwise disfavoured Michael addition in >60 fold selectivity over a competing ...

Low-temperature transient liquid phase bonding via electroplated Sn/In–Sn metallization
Journal of Materials Research and Technology, 2022 Sn/In–Sn bonding interfaces obtained by the transient liquid phase (TLP) reaction were investigated for applications in low-temperature assembly. Bonding was achieved at temperatures below 150 °C with a low bonding pressure.

The Power of the Mechanical Bond [PDF]
Chem, 2018 In this issue of Chem, Stoddart and co-workers present a strategy for preparing positively charged catenanes bearing ≤7.3 charges per cubic nanometer through a templation approach. Using Cu as both a reducing agent and catalyst, they produced an enthapically and entropically demanding 12+ charged [3]catenane and 24+ charged [5]catenane.
