A series of calix[4]arene based ditopic receptors possessing bipyridyl and hydrazone units have been synthesized and evaluated for ionic recognition. It has been observed that the synthesized derivatives function as allosteric receptors for simultaneous recognition of Co 2+ and F − ions through non-covalent interactions. Significant bathochromic shifts in the UV–visible spectrum with...
A series of novel calix[4]arene-based neutral semicarbazone and thiosemicarbazone receptors have been synthesized and characterized. The molecular receptor 4a recognizes HSO4- in preference to other anions (Cl − , Br − , I − , ClO4-, H2PO4- and PF6-) through a 1:1 binding-stoichiometry.
