摘要
Two isostructural cadmium complexes [Cd4(2-abpt)2(H2O)2X8]·2H2O (X?=?Cl (1), Br (2)) based on multidentate chelating ligand 4-amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole (2-abpt) with discrete tetranuclear structures have been synthesized and display halogen-modulated photochromic behaviors and switchable photoluminescence. Importantly, their colored photoproducts possess hydrogen-bonding interactions induced ultralong-lived charge-separated state and acetonitrile erasable behavior.
