CO release with ratiometric fluorescence changes: a promising visible-light-triggered metal-free CO-releasing molecule†
Abstract
The first visible-light-triggered metal-free and ratiometric fluorescent CORM is reported. This CORM can be used to release CO with distinct ratiometric fluorescence changes in aqueous solution, living cells, zebrafish, and mice, which provided an excellent controllable and trackable CORM for living systems.
