Architecture-Controllable Single-Crystal Helical Self-assembly of Small-Molecule Disulfides with Dynamic Chirality.

14 − 16 The most famous example is Pasteur’s discovery in 1848 showing the separation of tartrate enantiomers by crystallization, which later opened the area of structural chemistry highly significant to organic chemistry and biochemistry. 17 Prominent is also the role of chirality related to material science, i.e., the tactility effect of macromolecules. 18 The relative stereochemistry of adjacent stereogenic units within a polymer remarkably determines the interchain interactions, crystalline degree, and thus material properties (e.g., melting point, glassy transition temperature, mechanical performance, thermal stability). 19 The fundamental stereochemical principles based on static chiral molecules have been reasonably well understood.
