Abstract
Convenient methods of the synthesis of new perfluoroaromatic monomers of BB and AB types and polyimides on their basis were developed. The effect of the structural factors (the nature of aromatic framework, substituents and bridges, isomerism) on the reactivity of monomers and major characteristics of polyimides was discussed. It was established that the obtained polyimides possess promising properties for optoelectronic applications.
