Abstract
Two novel molecular probes bearing two urea (sensor 1) or thiourea (sensor 2) groups (as anion recognition site) coupled with a nitrophenyl group (chromogenic unit) were synthesized and evaluated according to the binding site-signaling subunit approach.The behavior of these different compounds toward metal ions (Co2+, Ni2+, Cu2+, Zn2+, and Cd2+) and anions (Fâ, Clâ, Brâ, Iâ, ClO4â, NO3â, CNâ, OHâ, CH3COOâ, and H2PO4â) was investigated by UV-vis spectroscopy in DMSO.
