| Popis: | 102 For the preparation of organic receptors for specific anions, we successfully synthesized three ligands (L5,L6, L8) containing pyrrolyl and amino functionalities. L5with three pyrrolyl groups can be converted to protonated L6, [HL6]+, in the presence of acids and pyrrolylaldehyde. Cation [HL6]+with four pyrrolyl groups is able to selectively capture HSO4and SO42anions as precipitates in ethanol. In addition, protonatedL5can selectively form precipitates with HSO4and H2PO4anions in ethanol. Interestingly, the protonated L8with two pyrrolyl groups selected to precipitate H2PO4anions with high fidelity in ethanol. All complexes mentioned above were characterized by NMR, EA, and X-ray analyses. |
