Abstract
Described herein are compositions and methods for the storage and release of hydrogen gas using covalent organic frameworks (COFs). Advantageously, the compositions and methods described herein may be used for the facile and rapid release of hydrogen gas at near ambient temperatures. The described COFs allow for photoactivation, where the release of gas is initiated or the rate of release is increased with the COF is exposed to electromagnetic radiation, for example, UV light.
