摘要：

Thin films of (TTF)(TCNQ) (TTF = tetrathiafulvalene, TCNQ = tetracyano-acyanoquinodimethane) are deposited on Si (001), KBr and stainless steel conversion coatings (SSCC) using chemical vapor deposition. These films are characterized by IR, XRD, conductivity measurements, and SEM. Conducting nanowires and nanorings of (TTF)(TCNQ) and nanowires of (TTF)[Ni(dmit)(2)](2) (typically, 20 nm x 20 mum) are prepared by successively dipping SSCC in acetonitrile solutions of TTF and TCNQ, or (TTF)(2)(BF(4)) and (Bu(4)N)[Ni(dmit)(2)], respectively. These nanowires are observed by SEM. The (TTF)(TCNQ) nanowires are also observed by TEM and AFM and characterized by current-voltage measurements. Nanowires of (TTF)[Ni(dmit)(2)](2) are also obtained on silicon conversion coatings (SiCC) and characterized by Raman spectroscopy.
