Pinene is a family of bicyclic monoterpenes found in nature, which exhibits important applications in chemical industry and biomedicine; however, the discrimination methods used for pinene enantiomers are still rare. The alpha- and beta-pinene enantiomers were recognized and discriminated via an electrochemical method for the first time based on a cyclodextrin metal-organic framework (CD-MOF) as an electrochemical chiral sensor. Four pinene isomers were successfully recognized and enantiomeric discriminated via an electrochemical method using a chiral gamma-cyclodextrin metal-organic framework as a sensor.
