摘      要：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 × 10^8 L/mol. The complexation of the receptors with anions was further unambiguously confirmed by single-crystal X-ray analysis
