New possibilities for the effective influence on the charge transport in poly(arylene ether ketones) without using phthalide-containing fragments in the polymer chains

A number of copoly(arylene ether ketones) containing the phenolfluorene and bisphenol A fragments were synthesized. By the example of these compounds, it was shown for the first time that the effect of reversible electronic switching can exhibit in the copolymer films even if this effect is absent in the corresponding homopolymer films.
