A water-soluble fluorescent CO2gas probe based on a tetraphenylethene derivative (TPE-ONa) has been developed. After bubbling CO2into the detection solution, a remarkable color change and fluorescence enhancement could be observed. A porous film was successfully fabricated by mixing TPE-ONa with sodium carboxymethyl cellulose in water, which can serve as an efficient CO2gas detection system. More importantly, TPE-ONa exhibits low cytotoxicity towards live cells and has the ability to monitor the external CO2concentration changes of living cells.
