Mechanophore activation at heterointerface and surface crowdedness as a determining factor
"When bringing ""mechanical force"" and ""polymer"" into conversation, one might naturally relate to everyday scenarios such as worn cloth, broken taillight and cracked paint. The intuitive viewpoint reflects the historic consensus that mechanically induced chemical changes are destructive. …

Polymer architecture effects on mechanochemical reactions
Long chain polymers have a unique ability to become highly extended in elongational flow fields. The forces developed along the backbone give rise to scission of the chains near their center. Recently, this unique property of polymers has been adopted to explore new chemical transformations by …

Chemomechanics with a molecular force probe
… to relate the key features of a photoactuating polymer to the force-dependent kinetics of the actuating and side reactions of its monomer. Experimentally measured kinetic parameters for both photo- and thermal isomerizations of the C=C bond in a series of stiff stilbene macrocycles as a function …
