Dramatic emission enhancement of aggregation-induced emission luminogens by dynamic metal coordination bonds and the anti-heavy-atom effect

Abstract

Restriction of intramolecular motions of AIEgens is greatly intensified by introducing dynamic metal coordination bonds to achieve dramatic fluorescence enhancement, which provides a simple and effective way to dramatically improve the emission efficiency of AIEgens. AIEgen-based metal complexes have an abnormal anti-heavy-atom effect, which contributes to their high emission efficiencies without changing their emission nature.
