摘要: Abstract A thiophene-functionalized monomer 1-phenyl-2,5-di(2-thienyl)-1H-pyrrole (PTP) was synthesized. The chemical polymerization of PTP (CPTP) realized by using FeCl 3 as the oxidant. structures both and soluble polymer were investigated Nuclear Magnetic Resonance ( 1 H 13 C NMR) Fourier Transform Infrared (FTIR). average molecular weight chemically synthesized determined gel permeation chromatography (GPC) Mn = 7.2 × 10 . electrochemical oxidative carried out via constant-potential electrolysis. Characterizations resulting done cyclic voltammetry (CV), FTIR, Scanning Electron Microscopy (SEM) UV–vis Spectroscopy. conductivity sample measured four-probe technique. Moreover, spectroelectrochemical electrochromic properties film investigated. Spectroelectrochemical analysis P(PTP) revealed electronic transitions at 413, 577 884 nm corresponding to π–π * transition, polaron, bipolaron band formations, respectively. Kinetic studies evaluated switching ability P(PTP); percent transmittance T % found 27%. homopolymer used construct dual-type devices (ECDs) against poly(3,4-ethylenedioxythiophene) (PEDOT). Spectroelectrochemistry, open circuit stability
