Abstract

Structural features of localization of chiral isomers of 1-phenylethanol (R-PhEtOH and S-PhEtOH) and their mobility activation in homochiral metal-organic [Zn2 (bdc)(S-lac)(dmf)] sorbent were studied with (1)H and (13)C NMR methods. (13)C NMR chemical shifts do not show obvious advantage of selective interaction of molecule guests. But activation molecular mobility of S-PhEtOH and R-PhEtOH clearly indicates that stabilization of [Zn2(bdc)(S-lac)(dmf)]·S-PhEtOH structure is more preferable than stabilization of [Zn2 (bdc)(S-lac)(dmf)]·R-PhEtOH structure.

Keywords: 1-phenylethanol enantiomers; 1H and 13C NMR; homochiral metal-organic sorbent.
