Towards modulating the colour hues of isoindigo-based electrochromic polymers through variation of thiophene-based donor groups

Abstract

Conjugated polymers containing isoindigo electron acceptor groups have gained attention for electrochromic (EC) applications in recent years. To obtain a deeper fundamental understanding of the EC properties of isoindigo-based conjugated...

Molecular level understanding of the chalcogen atom effect on chalcogen-based polymers through electrostatic potential, non-covalent interactions, excited state behaviour, and radial distribution function

“…2,3 Mostly polymer donors are designed as donor-acceptor alternative conjugated polymers using a suitable combination of electron-rich and electron-deficient groups. 4,5 This is an efficient way to achieve push-full characteristics that are necessary for free charge generation. The strength of electron-rich and electron-deficient groups controls the interaction between polymer molecules as well as the interaction between them and their counterparts.…”

Pyrrolo[3,4-c]pyridine-1,2-dione: a new electron acceptor for electrochromic conjugated polymers

“…Arylamines, thiophene and its derivatives such as 3,4-ethylenedioxythiophene (EDOT) and thieno[3,2- b ]thiophenes are common electron donors used in EC polymers, whereas common electron acceptors include BTD, BTZ, and quinoxalines. 48,49 For imide-based acceptors, in addition to the more frequently-reported DPP 50–52 and isoindigo, 53–55 the use of alkyl-POSS-substituted phthalimide acceptor coupled with EDOT donors has been reported by Cihaner and Önal et al ., which reveal grey to purple colour switching. 56 Likewise, EC polymers containing other analogous imide-type acceptors, including thiophene imide, 57–59 naphthalene diimide, 60,61 and perylene diimide, 62,63 were also studied.…”

Synthesis, DFT investigations, antioxidant, antibacterial activity and SAR-study of novel thiophene-2-carboxamide derivatives

“…It is known that heterocyclic compounds containing sulfur in their structures are used widely to eliminate free radicals and stop the antimicrobial resistance in addition to other pharmaceutical applications [ 5 – 7 ]. Generally, thiophenes have wide applications in different fields such as solid-state electrochromic devices [ 8 ], industry and medicinal chemistry. They possess biological properties such as antioxidant [ 9 – 16 ], antibacterial [ 17 – 19 ], antifungal [ 20 – 22 ], inflammatory [ 23 ] and antitumor [ 24 – 26 ].…”
