Mechanochemistry
The scientific community’s general interest in using mechanical energy to trigger or facilitate chemical reactivity has been growing at a speedy pace. In particular, in recent years, organic chemistry has witnessed a constant flow of examples where the use of mechanochemical techniques proved not only to outperform traditional solution-based methodologies, but also enabled access to otherwise i...
متن کاملPhotoinduced transformations of stiff-stilbene-based discrete metallacycles to metallosupramolecular polymers.
Control over structural transformations in supramolecular entities by external stimuli is critical for the development of adaptable and functional soft materials. Herein, we have designed and synthesized a dipyridyl donor containing a central Z-configured stiff-stilbene unit that self-assembles in the presence of two 180° di-Pt(II) acceptors to produce size-controllable discrete organoplatinum(...

متن کاملEnhancing covalent mechanochemistry in bulk polymers using electrospun ABA triblock copolymers.
The mechanochemical activation of covalent bonds in bulk polymers is often characterized by low conversions. Here we report that the activation of gem-dibromocyclopropane (gDBC) mechanophores embedded in a poly(1,4-butadiene) (PB) is enhanced when a central gDBC-PB block is flanked by two polystyrene (PS) end blocks in an ABA-type triblock architecture. Electrospinning the PS-(gDBC)PB-PS leads ...
متن کاملMechanochemistry: an overview*
The field of mechanochemistry is reviewed. A large number of mechanochemical reactions are described as well as industrial applications. INTRODUCTION At the beginning of this century, W. Nernst classified the different fields of chemistry according to the type of energy supplied to the system: thermochemistry, electrochemistry, photochemistry, etc. The name mechanochemistry was applied to the f...
