Metal-organic Frameworks as Potential Shock Absorbers: The Case of the Highly Flexible MIL-53(Al)

Chem Commun (Camb). 2014 Aug 28;50(67):9462-4. doi: 10.1039/c4cc03853c.

Abstract

The mechanical energy absorption ability of the highly flexible MIL-53(Al) MOF material was explored using a combination of experiments and molecular simulations. A pressure-induced transition between the large pore and the closed pore forms of this solid was revealed to be irreversible and associated with a relatively large energy absorption capacity. Both features make MIL-53(Al) the first potential MOF candidate for further use as a shock absorber.
