Synthesis and Properties of PPV–Based (η⁶–Arene)Cr(CO)3–Containing Polymers Having Alkyldiphenylamine or Triarylamine in the Main Chain

Summary

Novel poly(p–phenylenevinylene)–based (η⁶–arene)Cr(CO)3–containing polymers including the alkyldiphenylamine or triarylamine units in the main chain were synthesized by the Homer–Wadsworth–Emmons coupling reaction. The structures of the polymers were confirmed by NMR and FT–IR spectra. The polymers were soluble in common organic solvents such as THF, CHCl₃, and CH₂Cl₂. The polymer showed interaction between the electron–withdrawing (η⁶–arene)Cr(CO)³ unit and the unshared electron pair on the nitrogen atom along the polymer backbone.
