Synthesis and anion coordination chemistry of new calix[4]arene pyridinium receptors
New lower rim substituted calix[4]arene bis-pyridinium receptors L1, L2 and a novel lower rim bridged calix[4]arene pyridinium receptor L3 have been prepared and shown to bind a variety of anionic guest species. Proton NMR titration studies in deuteriated DMSO solutions reveal L1 and L2 to complex H...

| description | New lower rim substituted calix[4]arene bis-pyridinium receptors L1, L2 and a novel lower rim bridged calix[4]arene pyridinium receptor L3 have been prepared and shown to bind a variety of anionic guest species. Proton NMR titration studies in deuteriated DMSO solutions reveal L1 and L2 to complex H2PO4-, Cl-, Br-, HSO4-, anions with L:2X- stoichiometry with L1 exhibiting a selectivity preference for H2PO4-. L3 forms 1:1 stoichiometric complexes with Cl- and Br- of similar stability. Cyclic voltammetric investigations have demonstrated L1 to electrochemically recognise H2PO4- and Cl- anions. |
