Carbon monoxide (CO) is a colorless and odorless gas often used as a fuel and as an important raw material for the synthesis of basic organic compounds in the chemical industry. CO affects respiration and organ coordination in organisms, and is fatal at high concentration. Due to the wide range of industrial applications and biological effects of CO, its research has received considerable attention from researchers. In this study, we designed and synthesized a chemiluminescent sensor CL-CO, which can recognize CO in the presence of palladium chloride (PdCl2), based on the Schaap’s adamantylidene-dioxetane system and allyl ether as the recognition site. In both liquid and solid states, CL-CO can recognize CO gas with high sensitivity and selectivity. This work provides a convenient tool for studying CO gas, and a new application for exploring the adamantylidene-dioxetane system. [Display omitted] •A new chemiluminescence probe for detecting CO was designed.•The probe has very high sensitivity and selectivity for CO released from CORM-3 solution and CO gas.•Whether probe is liquid or solid, it can recognize CO gas.•The detection of gas by chemiluminescence probe is realized in a new way.
