Detection of cobalt(II) and copper(II) selectively using versatile fluorochemosensors in parts per trillion level in aqueous solution

Abstract The tetra terpyridyl appended porphyrin was used for the detection of Co(II) and Cu(II) ions in aqueous media. The porphyrin was synthesized by condensation of a Formyl Phenyl Terpyridine and pyrrole. The fluorescence response and Binding constant value predicated the strong affinity of the fluorophore specifically for Co(II) ion followed by Cu(II) ion. All the metal ion can be detected in 10-11 M concentration.
