Pyrene Derived aggregation-induced emission sensor for highly selective detection of explosive CL-20

Abstract

With the increasingly severe international situation, explosive detection has become an important topic of national security, and the rapid and efficient chemical sensors have attracted people's attention. In this work, a novel sensor CSA was synthesized through cholesterol succinate and 1-Aminopyrene. UV–vis and fluorescence spectra showed that CSA had a typical aggregation-induced emission （AIE） effect in THF/H2O solution, and explosive CL-20 could effectively quench this fluorescence. Also, the seal and cotton swab prepared by CSA can specifically detect CL-20, providing a platform for the practical application of CSA in public safety.
