Abstract: Quasi-one-dimensional microstructures of metal-organic complex Ag(TCNQ) were prepared by chemical solution reaction method. The obtained Ag(TCNQ) samples were characterized as crystalline state by XRD.SEM observation showed that Ag(TCNQ) was quasi -one-dimensional micro tube or wire. Raman measurement showed that complete charge transfer occurred between Ag atom and TCNQ molecule during the formation of Ag(TCNQ) single microstructure. The effects of thickness of Ag films and reaction time on the formation of quasi-one-dimensional microstructure of Ag(TCNQ) were studied. The results show that the thinner the Ag film is, the sparser the Ag(TCNQ) microstructures is obtained. The changes of morphologies for different reaction time indicate that the reaction undergoes three stages, i.e. formation and growth of crystals, complete reaction, and dissolving, orderly.

Key words: Metal-organic complex, Ag(TCNQ), Quasi-one-dimensional microstructure
