A novel fluorescence chemical sensor-based probe 1-{[(E)-(2-aminophenyl)azanylidene]methyl}naphthalen-2-ol (AMN) was designed and synthesized, which performed a "naked eye" detection ability toward Cu and Co based on aggregation-induced emission (AIE) fluorescence strategy. It has sensitive detection ability for Cu and Co. In addition, the color changed from yellow-green to orange under the sunlight, realizing the rapid identification of Cu/Co, which has the potential of on-site visual detection under the "naked eye".

Various greatly influential parameters were optimized using a Box-Behnken design (BBD) through the response surface methodology (RSM) to obtain more satisfactory recovery. Under optimum conditions, the method detection limits (MDLs) were in the range of 0.
