Abstract

original image

Alkoxy-functionalized porous metal–organic frameworks show extreme anisotropic thermal expansion and can reversibly switch between narrow and large pore forms. Flexible alkoxy chains are covalently attached to the crystalline scaffold but exhibit conformational flexibility. The substituents can be viewed as immobilized guests whose thermally induced vibrations trigger a structural response of the entire framework. The detailed thermo-mechanical response of these materials is fine-tuned by S. Henke, A. Schneemann, and R. A. Fischer on page 5990.
