Chemoselective palladium-catalyzed arylation of polyamines with 6-bromoquinoline was explored to prepare chelators for the detection of metal cations in aqueous media. The introduction of a single aromatic moiety into non-protected polyamine mols. was achieved using the com. available Pd(dba)2/BINAP precatalyst to afford nitrogen chelators, in which the aromatic signaling unit is directly attached to the polyamine residue. Water-soluble receptors were then synthesized using N-alkylation of these polyamines by hydrophilic coordinating residues. By combining rich photophys. properties of the 6-aminoquinoline unit with a high coordination affinity of chelating polyamines and a hydrophilic character of carboxamido-substituted phosphonic acid diesters in a single mol. device, the authors synthesized chemosensor 5 for selective double-channel (UV-visible and fluorescence spectroscopies) detection of CuII ions in aqueous media at physiol. levels. This receptor is suitable for the anal. of drinking water and fabrication of paper test strips for the naked-eye detection of CuII ions under UV-light. By increasing the number of donor sites the authors also obtained chemosensor 6 which is efficient for the detection of HgII ions. Moreover, chemosensor 6 is also suitable for multiple detection of metal ions because it chelates not only HgII but also CuII and ZnII ions displaying different responses of emission in the presence of these three cations.
