Summary:Stimulus-responsive chromic materials show important applications in anticounterfeiting, sensor encryption, and catalysis. Herein, [Zn2(H2O)­(TPTz)­(C2O4)2]·5H2O (1, TPTz = 2,4,6-tris-2-pyridyl-1,3,5-triazine, C2O4 2– = oxalate) with a one-dimensional chain structure was synthesized and detailly studied via spectral analyses. 1 displayed versatile stimulus-responsive chromic properties, exhibiting a spectrum of colors ranging from light yellow to light orange under light, transitioning to white under heat, and manifesting as light pink in amine vapor, in response to various stimuli. The electron-transfer (ET)-dominated chromic mechanisms were characterized using UV–vis, photoluminescence, and electron paramagnetic resonance spectra. In addition, we explored the application of this multistimulus-responsive material for inkless printing and ethylenediamine detection. This work inspires further design of ET-dominated multistimulus-responsive chromic materials in molecular materials.
