Abstract
The weak and reversible nature of hydrogen bonds endows porous materials with structural flexibility. In this article, we highlight structural transformations involving the cleavage and reformation of hydrogen bonds-termed H-bond reformation. To enable control over H-bond reformation through molecular design, we examine and discuss key structural features. Particular attention is given to tetracarboxylic acids bearing 4,4'-dicarboxy-o-terphenyl moieties as scaffolds for inducing H-bond reformation. These insights are expected to guide the rational design of dynamic porous materials with tunable properties and stimuli-responsive behavior.
