A series of carbazolylurea and carbazolylthiourea-based receptors have been synthesized and their anion complexation and fluorescence properties studied. The urea compounds show selectivity for oxoanion complexation over chloride and the fluorescence of compound 1 is selectively quenched by benzoate anions in DMSO/0.5% water. However the thiourea compounds show reduced anion affinities compared to the urea analogues.
