Eugenol nicotinicate-silver (I) complex, and preparation method and use thereof

The invention discloses an eugenol nicotinicate-silver (I) complex, and a preparation method and a use thereof, and relates to a new compound acetylaminophenyl nicotinicate-silver (I) complex, and a preparation method thereof. The compound has a chemical formula represented by [AgL(NO3)]n, wherein L is eugenol nicotinicate, that is (4-allyl-2-methoxy)phenyl nicotinicate, the complex is a one-dimensional structure with an unusual coordination mode, the metal Ag (I) center is a four-coordinate mode, four coordination atoms are two carbon atoms, a nitrogen atom and an oxygen atom respectively, the two carbon atoms are from the olefin of a ligand, the nitrogen atom is from the pyridine ring of another ligand, and the oxygen atom is from a nitrate ion. Ligand molecules are connected through the metal Ag( I) to form a one-dimensional chain structure. The one-dimensional structure forms a two-dimensional layered structure through Ag-O weak action, and a three-dimensional structure is formed through C-H...O hydrogen bond weak action. The complex has a stable fluorescence performance.
