Abstract:
An efficient and highly selective colorimetric and fluorescent receptor DTPDA has been synthesized for sensitive detection of Pb(2+) and Fe(3+) cations. The sensor DTPDA produces a facile, cost-effective and naked eye sensing platform to determine trace amounts of Pb(2+) and Fe(3+) metal ions by complexation with pendent S-termini of thiophenes, which commonly coordinates to central N-termini of pyridine.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
