Solution processable donor acceptor type dibenzothiophen-S,S-dioxide derivatives for electrochromic applications

A Solution‐processible, n‐dopable polypyrrole derivative

“…In accordance with the literature,22 PyNI (50 mg) and FeCl 3 (47 mg) were dissolved in chloroform (8 mL) and nitromethane (5 mL) under argon atmosphere, respectively. FeCl 3 solution was added dropwise to the monomer solution.…”

Molecular design of DBT/DBF hybrid thiophenes π-conjugated systems and comparative study of their electropolymerization and optoelectronic properties: from comonomers to electrochromic polymers

“…The longer the wavelength of the absorption is, the higher will the polymer displayed the Polymer Chemistry Paper conjugation length. 31 Therefore, compared with comonomers, the red shifts for polymers were due to their longer chain length. These spectral results confirmed the occurrence of electrochemical polymerisation.…”

“…[26][27][28] Our group recently synthesized two novel blue-light-emitting DBT/DBF end-capped with EDOT monomers (Scheme 2), and the corresponding polymers via their electropolymerization displayed good electrochromic properties. 29 Camurlu et al 30,31 investigated the synthesis, optical and electrochromic performance of donor-acceptor-donor type monomers: THSO 2 and EDOTSO 2 (Scheme 2) and used in organic electronic applications. Overall, in comparison with fluorene/carbazole, DBT/ DBF-based polymers (as well as their derivatives, Scheme 2) have attracted less attention as electroactive materials.…”

Highly Regiosymmetric Homopolymer Based on Dioxythiophene for Realizing Water-Processable Blue-to-Transmissive Electrochrome

“…To allow materials to be incorporated into the large area device architecture of interest, great efforts have been made over the last 2 decades to synthesize novel, especially solution-processable, electrochromic polymers (SPECP) which can be switched from colored neutral state to transmissive oxidized state. − …”
