Eight novel three-dimensional homochiral
helical metal–organic
frameworks (HHMOFs), namely, [Cd3((S)-PIA)2(PPA)(H2O)2]n (1-L), [Cd3((R)-PIA)2(PPA)(H2O)2]n (1-D), [Cd4((R)-PIA)3(DPP)4(H2O)4]n (2-D), [Cd1.5((S)-PIA)(4,4′-DIB)2]n (3-L), [Cd1.5((S)-PIA)(DPEE)1.5]n (4-L), [Cd1.5((R)-PIA)(DPEE)1.5]n (4-D), [Cd1.5((S)-PIA)(DPEA)1.5]n (5-L), and [Cd1.5((S)-PIA)(DPEA)1.5]n (5-D) (H3PIA = 5-(2-carboxypyrrolidine-1-carbonyl)
isophthalic acid) have been synthesized using proline-derived ligands
((S)-H3PIA and (R)-H3PIA). Crystallographic analysis indicates that all the complexes
contain homochiral left- and/or right-handed helical chains, which
are constructed by PIA fragments and Cd(II) ions. Meanwhile, in these
complexes nitrogen heterocycle auxiliary ligands play an important
role in structural diversity. Some physical characteristics, such
as thermal stabilities, solid-state circular dichroism, and photoluminescent
properties, are also investigated. Our results highlight an effective
method to apply proline ligands to construct interesting HHMOFs.
