Chiral recognition in organogels occurs in the coassembly of the chiral gelator 1 with the chiral guest molecule 2 . The diastereomeric aggregates formed from ( R , R )‐ 2 with ( R , R )‐ 1 or ( S , S )‐ 1 were found to be truly different in structure and strength. Cooperativity makes a major contribution to the chiral recognition in this system.
