Abstract

The detection of o-nitrophenol in the environment is of great significance to environmental protection. In this paper, the fluorescence sensor of CsPbBr3@SHFW was synthesized by an ultrasonic assisted method using perovskite quantum dots as the fluorescence source and a super hydrophobic porous organic polymer framework (SHFW) as the protective layer. Then CsPbBr3@SHFW was used to detect o-nitrophenol in dichloromethane. Under the optimum conditions, the detection limit of CsPbBr3@SHFW was 7.69 × 10-3 μM, and the linear range was 0-280 μM. It was also proved that the fluorescence quenching of this work is electron transfer. This work provided help for the construction of a stable perovskite quantum dot sensor and the application of a perovskite quantum dot sensor in the field of fluorescence detection.
