The attachment of π‐conjugated chromophores that absorb the radiation with long wavelengths to poly(methylphenylsilylene) ( 1 ) via reactions of its formylated derivative is described. Some of the polymers obtained show improved photostability and higher quantum photogeneration efficiency in comparison with the parent polymer. Photoconductive ultra‐thin layers can be prepared from polar derivatives of ( 1 ) by the Langmuir–Blodgett technique.
