Functional Polymers: Selective Chemosensor for Group 8 Metal Ions
Kyu-Nam Kim, Young-Wan Kwon, Dong Hoon Choi, and Jung-Il Jin*
Many conjugated polymers can be used as sensory materials due to their strong fluorescence in the visible wavelength region. Jung-Il Jin and co-workers designed a new fluorescing poly(p-phenylene vinylene) (PPV) derivative containing two oligo(oxyethylene) (OE) pendants per repeating unit. These groups lead to a good water solubility and are able to form complexes with a wide variety of metal ions. Among the 25 different metal ions studied Fe(III), Os(III) and Ru(III) are found to effectively quench the fluorescence of the synthesized polymer rendering it a sensitive and selective chemosensor for these ions.
