Carbon monoxide (CO) is a colorless, odorless, toxic, and polluting gas produced by the incomplete combustion of carbon-containing substances such as coal and petroleum. CO is also a gaseous signaling molecule, which participates in and regulates a series of physiological and pathological processes. In this work, two kinds of CO-activated fluorescence probes 2 and 4 were designed and synthesized for the rapid detection of CO and evaluation of acute CO poisoning by hyperbaric oxygen therapy. Specifically, 2 and 4 both used the allyl formate group as the CO response unit and when they reacted wi...
