The authors create a zinc(ii) complex featuring a simple chemical structure but multi-functional luminochromism. Reversible dissociation/association between the zinc center and the terpyridine ligand plays a key role in the multi-functional luminochromism.

Achieving high contrast mechanochromism (Δ > 100 nm) and white-light emission under mild conditions from a single compound with a simple structure is a great challenge. Herein, we report a novel dual-emissive compound, namely SCP, with an asymmetric molecular structure that fully inherits the photophysical properties of the parent molecules SC and SP. SCP shows high contrast, linearly tunable mechanochromism and bright white-light emission arising from a combination of traditional fluorescence and thermally activated delayed fluorescence (TADF).
