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]
Summary
We report on the elastic moduli of two large pore zeolitic metal– organic frameworks (rho- and sod-ZMOF).
