Abstract

The structural and electrical properties of a new organic conducting polymer bearing a tetrathiafulvalene backbone whose termini are capped with the thioacetyl group were investigated. AFM observations indicated that on a gold surface, the polymers form rigid rod-like structures with a stretched length of about 50nm, which is comparable to its average length (∼60nm). The current-voltage characteristic exhibited semiconducting behavior with a conductivity of 1.0×10-5 Scm-1. A doping measurement was also performed using iodine. The current was enhanced 10 2-104 times after doping indicating the highly electron-donating nature of the polymer.
