Type: article
Abstract: Herein, a tripyridyl-triazine-based cadmium chloride complex CdCl2(2-TPT) (1) (2-TPT = 2,4,6-tri(2-pyridyl)-1,3,5-triazine), has been successfully synthesized by the solvothermal method. Complex 1 exhibits photochromic performance with color changing from colorless to grey. The structure, photochromic properties, and mechanism of 1 were well demonstrated by Single-crystal X-ray diffraction, PXRD, FTIR, ESR, XPS, and UV-vis spectroscopy, as well as DFT computational studies. The results of the study indicate that the photochromic performance is induced via photo-introduced electron transfer (PIET) process from the electron-rich Cl atoms to the electron-deficient ligand 2-TPT, which was verified by DFT calculation.
