Abstract

Polymer 1, a poly(olefin) with pendant Schiff base units is prepared by reacting poly(allylamine) and 2-hydroxynapthaldehyde in methanol. The optical properties of 1 are investigated in THF:H2O (9:1) solvent system buffered at pH 7.0 +/- 0.1 using HEPES. When tested against a range of physiological and environmentally relevant cations 1 displays selectivity for Ag+ from changes in the UV-vis spectra with linearity established in the range of 10-60 mu M. The addition of Ag+ to a solution of 1 also causes a colour change from colourless to dark yellow meaning Ag+ is also detectable by the naked eye. In contrast, selectivity is observed for Mn2+ from changes in the emission spectra again with good linearity observed in the range of 0-50 nM. This is the first reported polymeric sensor capable of detecting both Ag+ and Mn2+ using two different detection modes. (C) 2009 Elsevier Ltd. All rights reserved.
