摘要

Anodic oxidation of difluorenes bridged by dimethylsilyl moieties leads to the formation of insoluble electroactive films. Compared to classical polyfluorenes and poly(9,9′-difluorenes), the polymer bridged through Si(CH₃)₂ or substituted by Si(CH₃)₃ units are more stable towards oxidation, their yield of polymerization are higher and the conjugation length deduced by their λ_max UV–vis absorption bands under their neutral state are more important.
