• particularly interesting result was that better performance could be achieved if one attaches bulky, hydrophobic groups directly to the stereocenter. The effect of such neighboring groups on the enantioselectivity highly depends on the distance they have to the stereocenter. Keywords: chirality; confinement

The materials exhibit chirality, and a good overview of important developments was given by
