For the development of fluorescent sensors, one of the key points is choosing the sensitive material. Here, we aim at evaluating, under strictly identical experimental conditions, the performance of three materials for the detection of dinitrotoluene (a volatile marker of trinitrotoluene) through various parameters: response time, fluorescence intensity, sensitivity, reversibility, reaction after successive exposures and long-term stability. This first study rendered it possible to select a conjugated molecule as the best sensitive material for the...
