A simple and effective route for one-dimensional Ag-TCNQ metal-organic micro structures

In this paper, a simple and effective route for the preparation of (1D) Ag-TCNQ microstructures has been demonstrated by simply dissolving silver nitrate and 7, 7, 8, 8-tetracyanoquindimethane (TCNQ) into N,N-dimethyl formamide (DMF) solution. Herein, DMF was used as both the solvent and the reducer for silver nitrate. Transmission electron microscope (TEM) and scanning electron microscope (SEM) have been used to characterize the morphologies of products. X-ray diffraction pattern (XRD) and Fourier transform infrared spectroscopy (FTIR) proved that the obtained products were in the form of the Ag-TCNQ phase I. The formation mechanism of products and the electrical properties of products were investigated. (C) 2007 Elsevier B.V. All rights reserved.
