Abstract

We report the low elastic modulus of a zeolitic MOF, along with stabilization against structural collapse by filling with solvent.

Highlights

  • We report on the elastic moduli of two large pore zeolitic metal– organic frameworks

  • Structural similarities with zeolites are clear; the Zn(imidazolate dicarboxylate)[4] unit of ZMOFs and the ZnIJimidazolate)[4] motif of ZIFs (Fig. 1) replace the primary SiO4 building unit of zeolites, though the ≈145° angle subtended between metal nodes is unchanged and results in identical network architectures across the three families.[4]

  • Recent work has suggested that basic structural motifs may play a much larger role than chemical functionality in determining physical properties such as compressibility, elastic moduli and structural rigidity under processing conditions.[6,7,8]
