A series of polyferrocenylsilane (PFS) random copolymers containing covalently bound pendant [C-60] fullerene groups, the first well-characterized metallopolymers with pendant C60 units, have been prepared and characterized. The fullerene content of the prepared copolymers ranges from 7 to 24% relative to monomer unit. The desired copolymers were synthesized in three steps: I metal-catalyzed ring opening polymerization of sila[l]ferrocenophanes was performed to synthesize random copolymers of poly(ferrocenylmethylphenylsilane-co-ferrocenylehloromethylsilane); the resulting random PFSs were then functionalized by reaction with 11-azido-1-undecanol to give PFSs with pendant azide groups; the desired donor-acceptor C-60-containing PFSs were then synthesized by the reaction of the azide group in the side chains with C-60 in toluene at 110 degrees C. The resulting C-60-containing PFSs are air-stable and soluble in aromatic solvents, chloroform, or THE The UV-vis spectra of these materials show broad absorption up to 800 nm. Thin films of these materials were examined as the active layer in rare examples of all solid-state sandwich-type diode devices based on ferrocene-fullerene dyads. The devices exhibit photoconducting and photovoltaic responses, with an open circuit potential of ca. 0.3 V under white light illumination.
