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.
