Mirror symmetry breaking and chiral amplification in foldamer-based supramolecular helical aggregates.
نویسندگان
چکیده
Spontaneous asymmetric generation of supramolecular chiral fibers was observed in the folding induced self-assembly of a lock-washer shaped foldamer. A secondary nucleation growth mechanism is proposed to explain the observed chiral amplification or deracemization of these supramolecular fibers.

Mirror symmetry breaking and chiral amplification in foldamer-based supramolecular helical aggregatesw
There are numerous examples of achiral or dynamically racemic molecules that generate chirality in one-, two-, or threedimensional crystals, polymers, liquid crystal or supramolecular assemblies. Such systems are particularly attractive for investigating asymmetric induction (i.e. mirror symmetry breaking) and chiral amplification. These conglomerate forming systems typically yield a stochastic...
متن کاملMirror Symmetry Breaking in Helical Polysilanes: Preference between Left and Right of Chemical and Physical Origin
From elemental particles to human beings, matter is dissymmetric with respect to mirror symmetry. In 1860, Pasteur conjectured that biomolecular handedness— homochirality—may originate from certain inherent dissymmetric forces existing in the universe. Kipping, a pioneer of organosilicon chemistry, was interested in the handedness of sodium chlorate during his early research life. Since Kipping...
متن کاملMirror symmetry breaking in cubic phases and isotropic liquids driven by hydrogen bonding.
Achiral supramolecular hydrogen bonded complexes between rod-like 4-(4-alkoxyphenylazo)pyridines and a taper shaped 4-substituted benzoic acid form achiral (Ia3[combining macron]d) and chiral "Im3[combining macron]m-type" bicontinuous cubic (I432) phases and a chiral isotropic liquid mesophase (Iso1[*]). The chiral phases, resulting from spontaneous mirror symmetry breaking, represent conglomer...

متن کاملAmplification of enantiomeric excess, mirror-image symmetry breaking and kinetic proofreading in Soai reaction models with different oligomeric orders.
A comprehensive kinetic analysis of three prototypical autocatalytic cycle models based on the absolute asymmetric Soai reaction is presented. The three models, which can give rise to amplification of enantiomeric excess and mirror-image symmetry breaking, vary by their monomeric, dimeric or trimeric order of the assumed catalytic species. Our numerical approach considered the entire chiral com...
