Abstract

A liquid-like poly(6-chloroindole) (L-P6CIn) was prepared via a chemical oxidative polymerization in ethanol/water miscible solvents. (NH4)2S2O8 was used as an oxidant and nonylphenol polyoxyethylene ether sulfate (NPES, CH3(CH2)8C6H4(OCH2-CH2)10SO3H) acted as the dopant agent. In contrast to the agglomeration behavior of the eigenstate poly(6-chloroindole) (E-P6CIn), such liquid-like poly(6-chloroindole) doped by NPES appeared as well-dispersed core–shell nanoparticles. Moreover, L-P6CIn was flowable at or near room temperature and was dissoluble in many solvents and exhibited a high electric conductivity of 2 S m−1 at room temperature and 10 S m−1 at 50 ℃. Also, L-P6CIn was a good blue-light emitter. The combination of the liquid behavior, excellent solubility, good electric conductivity, and blue photoluminescence property makes L-P6CIn a promising precursor for applications such as lightweight battery, super capacitor, and anti-corrosion of metals and organic laser.
