Development of a chiral host system tunable via changes in a 21-column packing structure

A tunable chiral host system was developed by the self-assembly of a chiral 21-column structure formed from (1R,2R)-1,2-diphenylethylenediamine and dicarboxylic acid. This host system can include guest molecules by changing the packing of a chiral 21-column enantioselectively.
