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+, Zn 2+, and Cd2+) and anions (F-, Cl-, Br-, I-, ClO4-, NO3 -, CN-, OH-, CH3COO-, and H2PO4-) was investigated by UV-vis spectroscopy in DMSO. © 2013 Elsevier Ltd.
