Absolute Asymmetric Photochemistry using Spontaneous Chiral Crystallization) Marcel Dekker 2004年10月 Topics in Current Chemistry 254, Organic Solid State Reactions WebChiral molecules are optically active, meaning they rotate polarized light. The non-superimposable mirror images of a chiral molecule are called enantiomers. The interesting thing about enantiomers is that they rotate polarized light in the exact opposite way of each other, so if one enantiomer rotates it +25, the other will rotate it -25.

WebNov 14, 2024 · Without external chiral intervention, it is a challenge to form homochirality from achiral molecules with conformational flexibility. We here report on a rational strategy that uses multivalent noncovalent interactions to clamp the molecular conformations of achiral D-A molecules.

WebAsymmetric molecules are always chiral. The following table shows some examples of chiral and achiral molecules, with the Schoenflies notation of the point group of the molecule. In the achiral molecules, X and Y (with no subscript) represent achiral groups, whereas X R and X S or Y R and Y S represent enantiomers.
