The synthesis, protonation behaviour and Zn 2+ coordination chemistry of a new photoactive polyamine exhibiting “off‐on‐off” fluorescence is presented. Addition of Zn 2+ reduces the width of the fluorescence window, which is centred around physiological pH, and sharply enhances the emission intensity. (© Wiley‐VCH Verlag GmbH & Co.
