Three tetraurea-appended porphyrin derivatives were synthesized and applied as anion receptors to complex with various anions, including F-, Cl-, Br-, I-, NO3-, HSO4-, and AcO-. The binding stoichiometries were all measured to be 1:1 and high binding abilities of these receptors toward the anions were demonstrated with the association constants of up to 1.1 x 10(8) L/mol. The complexation of the receptors with anions was further unambigu
