Planar chirality
![An planar chiral derivative of ferrocene, used for kinetic resolution of some racemic secondary alcohols[1]](/Images/godic/202502/03/Planar_chiral_ferrocene_derivative.svg0347.png")
Planar chirality is the special case of chirality for two dimensions.
Most fundamentally, planar chirality is a mathematical term, finding use in chemistry, physics and related physical sciences, for example, in astronomy, optics and metamaterials. Recent occurrences in latter two fields are dominated by microwave applications and micro- and nanostructured planar interfaces for visible and infrared light.
