✦ Synopsis

UV photoelectron spectra were measured for poly( 1,l '-ferrocenediyl) (PF) synthesized in a well controlled way. The spectra are similar to those of ferrocene and I, 1 '-biferrocene, indicating limited electron delocalization. The ionization threshold energy was found to be 5.1 eV. Comparison with related compounds and information from other techniques indicate that PF is a unique system with intermediate electron delocalization between highly delocalized z-conjugated polymers and well localized systems such as vinyl polymers. The limited increase in electric conductivity upon acceptor doping is ascribed to ineffective hole transport rather than difficulty in hole creation.
