| Abstract
| - A novel methodology for the evaluation of receptor arrangement in structurally flexible anion chemosensorswas developed and applied to map the binding site of a new pseudocyclic tristhiourea chemosensor (6).The syntheses of 6 and related macrocyclic chemosensor 10 (a model of the folded monomeric structureof 6) are reported. Both chemosensors were evaluated by titration with a variety of structurally differentanions in CH3Cl and DMSO, showing a common preference for F-, CH3CO2-, and H2PO4-. However,within this group of anions, the binding patterns of the chemosensors differed, indicating dissimilarity inthe arrangement of the binding sites of 6 and 10.
