Homochiral Metal–Organic Framework with Intrinsic Chiral Topology and Helical Channels

Presented
here is an unusual microporous metal–organic framework
(FIR-30) integrating helical channels, intrinsical chirality,
and permanent porosity. The structure of FIR-30 containing
three types of cages has two interpenetrating helical channel systems
with opposite handedness, which can be considered a surface with the
same topology as gyroid, and the generation of chirality is related
with the intrinsically chiral topology of FIR-30. The
results provide new insight toward the construction of chiral MOFs
with helical channels.
