Abstract

The synthesis, protonation behaviour and Zn2+ coordination chemistry of a new photoactive polyamine exhibiting "off-on-off" fluorescence is presented. Addition of Zn2+ reduces the width of the fluorescence window, which is centred around physiological pH, and sharply enhances the emission intensity. © Wiley-VCH Verlag GmbH & Co. KGaA, 2005.
