Abstract
The novel colorimetric receptors 2,3-bis-N-(9,10-diaza-anthracen-1-yl)-Nâ²-phenylurea and 2,3-bis-N-(9,10-diaza-anthracen-1-yl)-Nâ²-phenylthiourea have been prepared by the reaction of 2,3-diaminophenazine with phenylisocyanate and phenylisothiocyanate, respectively, in quantitative yields. The interaction and colorimetric sensing properties of receptor = 2 and 3 with different anions were investigated by naked eye, UV-vis and fluorescence spectroscopy in DMSO. The receptors effectively and selectively recognized biologically important Fâ, CH3COOâ, H2PO4- in the presence of other anions, such as Clâ, Brâ, Iâ and HSO4- in DMSO.
