Descrição

The synthesis, protonation behaviour and Zn2+ coordination chemistry of a new photoactive polyamine exhibiting ldquooff-on-offrdquo 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.
