Jun Zhang’s group developed a new kind of nonaromatic polymaleimides (A-PM) via anionic polymerization. By adjusting the reaction conditions, the emission colors of A-PM are readily tunable from blue, green to orange and red, which is rarely achieved in nonconventional luminophores. These unique properties endow A-PM promising for applications in encryption, ion detection, fingerprint identification, etc. This work not only sheds new lights on the rational regulation of photophysical properties of nonconventional luminophores, but also paves the way for their versatile applications.
