Homochiral porous coordination polymers with a rare utk topology and two types of uniform channels for enantioseparation

Abstract

A pair of enantiopure chiral porous coordination polymers (PCPs) with a rare utk topology were prepared using derivatives of L-/D-alanine and Zn(CH₃COO)₂·2H₂O. The framework integrated two types of parallel and uniform 1D channels that were constructed by self-stranding of three equal helical chains and a single helical chain. Among them, the right-handed PCP D-NTU-18 showed enhanced enantioseparation towards racemic 1-phenyl-1-propanol.
