| Popis: | The 1,3-di{bis(2-hydroxynaphthyl)}-2-aminothiophenylcalix [4]arene (L1) has been synthesized and characterized by nmr, mass, uv- vis, fluorescence spectroscopy. The in-situ mixing of receptor L1 and copper ions in 1:1 pattern forms metallo supramolecular complex [L1‐Cu2+] which recognizes l -histidine from among other essential amino acids in the emission spectrum. It seems that receptor L1 act as a primary sensor for cation recognition and as a secondary sensor for l -histidine. |
