英文摘要： Development of rapid and sensitive recognition technology and reproducible real-time visualization testing tools for sulfur dioxide (SO2) is beneficial for environmental monitoring, which will reduce the harm of excessively released sulfur dioxide on the environment and human health. Aiming to the real time and rapid detection of sulfur dioxide in atmosphere, this project is to design and fabricate some novel fluorescent aryl platinum complexes, which combine the principle of special capture, recognition and temperature directed release of SO2 with fluorescence signal output. The fluorescent arylplatinum complexes are effective for developing new type of high selectivity and high sensitive gas detection tools for sulfur dioxide from different sources. The main research contents include: (1) synthesizing fluorescent probes based on arylplatinum complexes with specific recognition function by fluorescent functionalized modifications; (2) exploring the sensitive response mechanism of the probe’s fluorescence enhancement and optimizing the visual signal model with multifarious fluorescence color; (3) investigating the principle and method of assembling the probes on different carrier materials and developing reproducible high sensitive gas detection tubes. On this basis, the qualitative and quantitative relationship between visualized fluorescent signal in tubes and gas concentration will be established. This project provides a new kind of rapid, sensitive identification technology and application method for SO2, also promotes the development of monitoring and control of environmental pollution.
