Abstract:

The increase of diversity and quantity of metallic ions released into the environment from domestic or industrial untreated waste demands its identification and quantification. Thus, the synthesis of chemosensors for detecting ions has emerged in the past decade, where several fluorescent organic dyes have been synthesized as optical sensors for metal ions in solution The detection of these metals may be based on the increase/decrease of the fluorescence intensity or even the fluorescence maximum displacement. In this way, this work reports the synthesis and photophysical characterization of new urea/thiourea compounds as potential optical sensors in solution.
