| Popis: |
Poly (2,5-thiophenediyl) (2) reacts with AsF5 in a gas phase reaction yielding Poly (2,5-thiophenediyl) complexes with cationic centers and AsF6 counterions (1). Polymeric complexes of the same structure are formed by gas phase reactions of AsF5 with thiophene (3) and 2,2-bithienyl (4) via an oxidative poly-condenzation reaction. Treatment of the polymeric complexes 1 with aqueous ammonia yields 2. These complexes are stable materials due to the strong electron donating property of the thiophene system. They may be handled without any special precaution. They have electrical conductivities as high as 0.02 Ω−1 cm−1 (activation energy: E = 0.04eV). A possible mechanism for the formation of the polymeric complexes 1 is proposed according to the KOVACIC polycondenzation reaction of aromatic hydrocarbons. |
