Abstract
A Cu(II) coordination complex (1) with Schiff ligand derived from diaminomaleonitrile was synthesized and characterized, in which the ligand is rigid, planar and conjugated. The complex 1 displays an interesting fluorescent property relative to solvents which can be turned-on by CH2Cl2 and CHCl3 solvent molecules. The mechanism of this selective fluorescence emission has been studied based on the crystal structure and the spectrum analysis. The tuning on and off fluorescence of complex 1 can be controlled by the process of supramolecular aggregation/deaggregation in different solvents.
