Influence of benzene ring number attached on non-conjugated 3,4-ethylenedioxythiophene derivatives for solid-state polymerization

Abstract

Based on an EDOT–CH₂–N(R)–CH₂–EDOT platform, we investigated the effect of the substituent on the nitrogen atom on solid-state polymerization. Detailed characterizations of the corresponding polymers were carried out and crystals of all the monomers were obtained for structural analysis. Our study revealed that the introduction of aromatic moieties makes SSP successful, which would greatly widen the scope of monomers. In addition, besides linker distance, the substitution on the CH₂–N(R)–CH₂ linker also plays an important role in the SSP behavior of monomers.
