Two rationally designed 4-nitrophenyl-based molecular clefts functionalized with thiourea (L 1 ) and urea (L 2 ) have been synthesized and studied for a variety of anions by UV-Vis and colorimetric techniques in DMSO. Results from the binding studies suggest that both L 1 and L 2 bind halides showing the order fluoride chloride bromide iodide; and oxoanions showing the order dihydrogen phosphate hydrogen sulfate nitrate perchlorate. Each receptor has been shown to form a 11 complex with an anion via hydrogen
