A novel homochiral metal–organic framework with an expanded open cage based on (R)-3,3′-bis(6-carboxy-2-naphthyl)-2,2′-dihydroxy-1,1′-binaphthyl: synthesis, X-ray structure and efficient HPLC enantiomer separation

A new homochiral MOF with an expanded open cage was synthesized and utilized as a chiral stationary phase for HPLC.
