Chiral Molecules on Achiral Surfaces

An isolated molecule, which is chiral in the gas phases, will necessarily be chiral on adsorption if the basic structure and conformation of the molecule are retained. 

The —5°, L ( + 5°, R) gives an improved interdigitation of t-butyl groups compared to the diastereoisomers +5°, L (-5°, R). (Reprinted with permission from Ref. [25], Copyright 2006, American Chemical Society.
