Synthesis and Electric Modulus Formalism of Novel Metal-Phthalocyanine Bridged Polymers
Tóm tắt
Novel nickel and copper phthalocyanine polymers, with uniformly carboxylic end groups and carbonyl groups as bridges linking the phthalocyanine units, were successfully prepared. Structural modelling and atomic absorption spectroscopy confirmed the network polymeric structure and suggested at least nine phthalocyanine units in each polymeric network. The dielectric properties of the prepared polymers were investigated over a wide range of frequencies at room temperature. The electric modulus formalism was used to study the conductivity relaxation in the prepared polymers. The collapsing of the real part of the conductivity function, σ’, at higher frequencies for both materials was observed indicating that the local molecular dynamics is due to the polymer conjugated backbone (functional and/or terminal groups) with no clear effect of the central metal.
