Donor–acceptor type neutral green polymers containing 2,3-di(5-methylfuran-2-yl) quinoxaline acceptor and different thiophene donors

The synthesis of new donor–acceptor polymers containing the 2,3-di(2-furyl) quinoxaline moiety: Fast-switching, low-band-gap, p- and n-dopable, neutral green-colored materials

“…The results clearly demonstrate that the coloration efficiencies of PFETQ and PFMTQ are much greater than that of PFTQ. By contrast with the reported polymer films containing 2,3-di (5-methylfuran-2-yl) quinoxaline as the acceptor [10], PFETQ and PMFEQ with the same ethylenedioxythiophene donor unit but different acceptors, showed a similar response time, while the PFETQ film displayed a prominently higher optical contrast (DT%) than PMFEQ. Analogously, the PFMTQ film exhibits fast response time, despite the fact that the optical contrast is a little inferior to that of PMFMQ.…”

“…A comparison between the PFTQ and PMFTQ films reveals a higher optical contrast and faster response time for PFTQ. Generally speaking, the switching properties of the newly synthesized polymers were superior to the previously reported ones [10] due to their stronger electron-accepting ability and the well-defined coplanarity of the 2,3-di(2-furyl) quinoxaline moiety that was used as a substitution. In light of the superior characteristics mentioned above, PFETQ, PFMTQ and PFTQ could be the better candidates for electrochromic display applications.…”

“…The electrochemical band-gaps of these three polymers have been reported to be between 0.90 and 1.20 eV, and all of them present significant ntype doping [10].…”

Multichromic Polymers Containing Alternating Bi(3-Methoxythiophene) and Triphenylamine Based Units with Para-Protective Substituents

“…For the physical meaning and calculation method of the above parameters, the reader is referred to previous reports [32]. The dynamic switching properties of PCMTPA and PMMTPA are presented in Table 3.…”

Synthesis, characterizations, and electrochromic properties of donor–acceptor type polymers containing 2, 1, 3‐benzothiadiazole and different thiophene donors

“…The good electrochromic properties obtained from P(EDOT-HT-Tz) film, which can also be seen in other EDOT-based electrochromic polymers, can be attributed to the regular polymerization of EDOT-HT-Tz inducing less deficiency in the polymer chain, and good properties achieved from the homopolymer Poly(3,4-ethylyenedioxy-thiophene) (PEDOT) may be another reason. 40,45,46 Table 2 summarizes the electrochromic properties of the prepared polymers in this work and similar reported polymers. It can be noted that the absorption band of neutral polymers can be greatly tuned after the incorporation of 3-hexylthiophene into the backbone.…”
