Expanding dynamic framework materials into COFs through HOF approach

Summary

In this issue of Chem, Samanta et al. discovered unique guest sorption induced dynamic and reversible structural expansion in a hydrogen-bonded cross-linked organic framework H_COF-6, which is originated from the flexible disruption and rearrangement of anion clusters, expanding the dynamic framework materials into the region of covalent organic frameworks (COFs) by taking advantage of both HOF and COF chemistry.
