Multi‐Stimuli Responsive Luminescence and Domino Phase Transition of Hybrid Copper Halides with Nonlinear Optical Switching Behavior
Abstract Although phase transition materials (PTMs) under external stimuli are of great research interest duo to their rich potential applications, it is still challenging to explore multi‐responsive PTMs. Herein, two different phases of organic–inorganic hybrid copper‐based halides, α‐ and β‐Gua3 Cu2 I5(Gua+=CN3 H6+), were synthesized by solvent evaporation method, which they crystalize in the noncentrosymmetric space group Fdd2 with zero‐dimensional structure and centrosymmetric space group C2/ c with one‐dimensional metal‐halogen framework, respectively. Interestingly, it is firstly demonstrated that Gua3 Cu2 I5 simultaneously possesses reversible PL conversion and NLO switching properties in response to thermal stimulus. Strikingly, apart from heat, its structural phase transition can also be triggered by crystalline‐phase‐recognition (CPR) and mechanical force. These new findings may pave a path for future exploration of PTMs with multiple physical properties..
