Among various kinds of chemosensors, fluorescent chemosensors offer distinct advantages in terms of sensitivity, selectivity, response time and in situ observation, and have attracted much attention recently. This review summarizes the progress of conjugated polymers based fluorescent chemosensors for ions. The molecular design, synthesis, mechanism and application of conjugated polymers based fluorescent chemosensors for cations are described in detail, and the developing orientation for further research is presented. Key words conjugated polymers; chemosensors; fluorescence; ion recognition (fluorescent sensor) 1 [ 7]
