A novel homochiral zeolite-like metal-organic framework (ZMOF), [(Cu4I4) (dabco)2]·[Cu2(bbimb)]·3DMF (JLU-Liu23, dabco =1,4-diazabicyclo[2.2.2]-octane, H2bbimb =1,3-bis(2-benzimidazol)benzene, DMF = N,N-dimethylformamide), has been successfully constructed to host unprecedented DNA-like [Cu2(bbimb)]n polymers with double-helicity. The host-guest chirality interplay permitted the induced formation of an unusual gyroid MOF with homochirality and helical channels in the framework for the first time, JLU-Liu23. Importantly, the enantiomeric pairs (23P, 23M) can be promoted and isolated in the presence of appropriate chiral inducing agents, affording enantioselective separation of chiral molecules as well as small gas molecules.
一种新型的手性沸石类似的金属-有机骨架（ZMOF），[(Cu4I4) (dabco)2]·[Cu2(bbimb)]·3DMF（JLU-Liu23，dabco = 1,4-二氮杂双环[2.2.2]-辛烷，H2bbimb = 1,3-双（2-苯并咪唑）苯，DMF = N，N-二甲基甲酰胺），已成功构建以容纳前所未有的具有双链性的 DNA 样[Cu2(bbimb)]n 聚合物。主体 - 客体手性相互作用首次允许在骨架中形成具有手性和螺旋通道的不寻常的各向异性 MOF，即 JLU-Liu23。重要的是，在手性诱导剂的存在下可以促进和分离对映体对（23P、23M），从而能够对手性分子以及小气体分子进行对映选择性分离。
