Fluorescent carbazolylurea- and carbazolylthiourea-based anion receptors and sensors

10.1080/10610271003637087

The research investigates the anion complexation and fluorescence properties of a series of carbazolylurea- and carbazolylthioureabased receptors synthesized by the researchers. The purpose of the study is to explore the potential of these compounds as selective anion receptors and fluorescent sensors. The key chemicals used in the research include carbazolylurea and carbazolylthioureabased compounds, tetrabutylammonium salts of various anions (such as benzoate, acetate, chloride, and dihydrogen phosphate), and solvents like DMSO and water. The study found that the urea compounds showed selectivity for oxo-anion complexation over chloride, with compound 1 selectively quenched by benzoate anions in DMSO/0.5% water. In contrast, the thiourea compounds exhibited reduced anion affinities compared to their urea analogues. The research concludes that carbazole ureas are effective hosts for oxo-anions and can function as selective fluorescent sensors for certain anions, while thiourea-based analogues do not always possess higher affinities for anions than urea-based systems.
