Abstract

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.
