Preparation of polymers containing Fe(0)-coordinated 2,5-diethynylsilole units

摘要

UV irradiation of poly(organosilanylene-2,5-diethynylenesiloles) in benzene with an excess of Fe(CO)5 led to the formation of Fe(CO)(3)-coordinated silole units in the polymer backbone. The Fe(CO)(3)-coordinated polymers exhibited suppressed pi-conjugation, relative to the parent non-coordinated polymers. Hole-transporting properties of poly(organosilanylene-2,5-diethynylenesiloles) were examined by the performance of EL devices containing the polymer layer as the hole-transport and Alq3 layer as the electron-transporting emitter.
