Synthesis and Characterization of Electroactive PEDOT Platform with -Octylphenotiazine Derivative

CODEN: MPCACD

Abstract

Poly(3,4-ethylenedioxythiophene) (PEDOT) was synthesized in the presence of a phenothiazine derivative (PTZN_C8). The aim of the research was to use phenothiazine (PTZ) as a doping ion, investigate the possibility of synthesis, and determine the influence of PTZN_C8 on the state of order of forming PEDOT chains. The synthesis of PEDOT in the presence of a PTZN_C8 by cyclic voltammetry allowed characterizing the polymer films by determining the accumulated charge capacity. Different synthetic protocols were used to obtain layers of PEDOT as a matrix and PTZ derivative as a substance that changed the structure of a material. Layers were investigated by Fourier Transform Infrared Spectroscopy (FTIR) to identify the presence of compounds incorporated during synthesis as well as to estimate the degree of polymerization calculated to characterize the length of chains. Ultraviolet-visible spectrophotometry (UV-Vis) spectra allowed drawing releasing curves of PTZN_C8 from the PEDOT matrix. Results showed that it is possible to synthesize PEDOT with PTZN_C8, but deposited PEDOT was modified in terms of the length of the chains—as the content of the PTZN_C8 was higher, the chains were shorter.
