CO2 has attracted significant attention due to its effect on global warming. Meanwhile, CO2 is also essential for the modern agricultural, food, environmental, oil, and chemical industries. Thus, the rapid and selective detection and measurement of CO2 is urgent. Since the simplicity, sensitivity, and especially non-destructive detection capacities of probes based on fluorescent molecules, fluorescence-based detecting techniques have become vital. In the past few years, remarkable developments in CO2 probes have been made, which markedly advance the environment, industry, and medical field. This review highlights the recent advances in various functional materials and small-molecule fluorescent probes for visualizing CO2. These fluorescent probes' design strategies, recognition mechanisms, optical properties, and practical applications were systematically discussed. This review is expected to promote the development of the CO2 relative field, not only in the fluorescent probe but also in the environment and industry. •The optical properties and design strategies of functional materials- and small molecule-based fluorescent probes for CO2 are reviewed.•The practical applications of CO2 fluorescent probes are presented.•The challenges and perspectives for the development of CO2 fluorescent probes are discussed.
