چکیده

Spontaneous emergence of solid state chirality and mirror symmetry breaking occurred upon crystallization from a small templated dynamic combinatorial library (DCL) of achiral macrocyclic imines, and depended strongly on the nature of library building blocks (amines, aldehydes, template cations and anions) and crystallization temperature.

The formation of a hydrated homochiral helix from an achiral zwitterionic salt, spontaneous chiral symmetry breaking and redox chromism of crystals.

A unique supramolecular helix assisted by water tetramers is obtained by static evaporation of aqueous solution of a zwitterionic salt, 1,1'-bis(4-carboxylatebenzyl)-4,4'-bipyridinium; spontaneous chiral symmetry breaking occurs in crystallization; interestingly, redox chromism behavior of crystals upon exposure to alcohol atmosphere has been observed.

Supramolecular Chirality: Solvent Chirality Transfer in Molecular Chemistry and Polymer Chemistry

Controlled mirror symmetry breaking arising from chemical and physical origin is currently one of the hottest issues in the field of supramolecular chirality. The dynamic twisting abilities of solvent molecules are often ignored and unknown, although the targeted molecules and polymers in a fluid solution are surrounded by solvent molecules. We should pay more attention to the facts that mostly...

نقش شکست تقارن بار در اختلاف انرژی بستگی هسته‌های آینه‌ای 15O-15N و 17F-17O

  Charge symmetry breaking potentials due to the exchange of pseudoscalar and vector mesons in mirror nuclei are considered. With the computation of coulmb energy along with the present charge symmetry breaking effects provide a reasonably accurate description of the binding energy differences between mirror nuclei.

The emergence of halophilic evolutionary patterns from a dynamic combinatorial library of macrocyclic pseudopeptides.

The increase of the ionic strength amplifies the species bearing acidic side chains from a bio-inspired dynamic combinatorial library of macrocyclic pseudopeptides, in close resemblance to the evolution observed for the proteins of halophilic microorganisms.
