Construction of convenient systems for isomer discrimination is of great importance for medical and life sciences. Here, we report a simple and effective chiral sensing device based on a highly ordered self-assembly framework. Cu²⁺-modified β-cyclodextrin (Cu-β-CD) was self-assembled to the ammonia-ethanol cotreated chitosan (ae-CS), and the highly ordered framework was gradually formed during the “re-growth” process of the shrinked ae-CS films. Tryptophan (Trp) isomers were well discriminated with the highly ordered framework by electrochemical approach. This study is the first example showing how an ordered structure influences chiral recognition.
