Benzothiadiazole bridged EDOT based donor–acceptor polymers with tunable optical, electrochemical, morphological and electrochromic performance: effects of solvents and electrolytes

Abstract

<p>We present systematic opto-electrochemical studies of D–A polymer films prepared using different electrolytes and solvents. Significant effects of both the factors on the optical, electrochemical, morphology and electrochromic properties were found.</p>

Electrochemical copolymerization of 3,4-ethylenedioxythiophene and dithienothiophene: influence of feed ratio on electrical, optical and electrochromic properties

“…In continuation of our work on the conjugated copolymers, 39–44 three copolymers based on PEDOT and PDTT were synthesized by using different feed ratios of monomers EDOT and DTT as 2 : 1, 1 : 1 and 1 : 2, respectively. Copolymer films were electrodeposited on the ITO-coated glass surface by electrochemical oxidation of monomers EDOT and DTT, via electro-copolymerization method in 0.1 M TBAClO 4 /MeCN solution.…”

Photophysical and redox properties of new donor–acceptor–donor (DAD) compounds containing benzothiadiazole (A) and dimethyldihydroacridine (D) units: a combined experimental and theoretical study

“…Many DAD compounds readily electropolymerize yielding good optical quality films on transparent electrodes. 10–16 Moreover, these films frequently show interesting electrochemical activity over a wide potential range since both D and A segments are often characterized by several reversible redox couples. 17 Thus, electrochemically prepared films are perspective electrochromic materials providing electrochromism not only in the visible range of the spectrum but also in near infrared, 10,18–21 which is of great technological interest.…”

Theoretical Design, Synthesis, Solvatochromic Studies and Non‐Linear Optical Properties of 3,4‐Ethylenedioxythiophene and 3,4‐ Propylenedioxythiophene based Copolymers

“…Thiophene based donor‐acceptor type organic conducting polymers showed impressive NLO properties [13,14] . Propylenedioxythiophene (PRDOT) and ethylenedioxythiophene (EDOT) are the trending thiophene based monomers which have shown tremendous performance as monomers for organic polymers with photocatalytic hydrogen production, [15] excellent thermal performance [16] attractive optoelectronic, [17] electrochemical [18,19] and electrochromic properties [20–23] and in light emitting diodes [24] . The flexible action of thiophene based monomers in diode components, field‐effect transistors, electroluminescent lamps, organic solar cells, nonlinear optical devices, organic LED, and other devices are an outcome of their effortless synthesis, good ionization potential, better charge carrying mobility, environmental stability, and the potential to adapt with varying chemical structures [25–31] .…”
