A Dual‐Stimuli‐Responsive Coordination Network Featuring a Reversible Wide‐Range Luminescence Tuning Behavior

We herein report a new coordination network that deforms in a smooth and reversible manner under either thermal or pressure stimulation. Concomitantly, the organic fluorophores coordinatively bound to the channel in a face‐to‐face arrangement respond to this structural deformation by finely adapting their conformation and arrangement. As a result, the material exhibits a remarkable dual‐stimuli‐responsive luminescence shift across almost the entire visible region: The emission color of the crystal gradually changes from cyan to green by heating and then to red by pressure compression. Furthermore, each stage exhibits a linear dependence of both the emission maximum and intensity on stimulus and is fully reversible.
