Nano molar detection of Cd(ii) ions by luminescent metallo-supramolecular polymer formation. Issue 47 (29th October 2015) - Delwar Hossain, Md.
Abstract : A Cd(ii )-based metallo-supramolecular polymer was first synthesized via the 1 : 1 complexation of Cd(ii ) ions with bis(1, 10-phenanthroline) bearing a fluorine moiety as a spacer. Selective sensing of Cd(ii ) ions by the luminescent polymer formation was successfully achieved with sensitivity down to 8 nM concentration. Abstract : A Cd(ii )-based metallo-supramolecular polymer (polyCd) was formed via the 1 : 1 complexation of Cd(ii ) ions with bis(1, 10-phenanthroline) bearing a fluorine moiety as a luminescent spacer. The stepwise complexation was observed in UV-vis spectral titration. Selective sensing of Cd(ii ) ions based on the luminescent polymer formation was successfully achieved with sensitivity down to 8 nM concentration.
