Synthesis and characterization of new redox-active polymers based on 10-(1,3-dithiol-2-ylidene)anthracen-9(10H)-one derivatives

Ionic metallo‐Schiff base polymers of VO2+, Zn2+ and Cu2+: Synthesis, characterization and solid‐state conductivity

“…Many researches have recently been devoted to the investigation of N , N ′‐bipyridinium compounds and complexes due to their unique properties . Also, the synthesis of redox‐active organic and metallo‐organic and/or ionic polymers is an area of current research aimed at realizing special characteristics such as semiconducting properties. Thus, the design of new ligands with special and different characteristics and combining them with metal ions open new horizons in materials architecture.…”

N-Cyanoimine as an electron-withdrawing functional group for organic semiconductors: example of dihydroindacenodithiophene positional isomers

“…34 These diones are also central building blocks in the synthesis of dicyanovinylene analogues para-IDT(=C(CN) 2 ) 2 and meta-IDT(=C(CN) 2 ) 2 . 34 Thus, non-enolizing diones para-IDT(=O) 2 and meta-m a n u s c r i t p t IDT(=O) 2 react with N,N-bis-(trimethylsilyl)carbodiimide in the presence of titanium tetrachloride [70][71][72]76 to provide target para-IDT(=NCN) 2 and meta-IDT(=NCN) 2 as green-brown powders with good yields of 61 and 70 % respectively ( Scheme 1). These syntheses are short (4 steps), easy to perform and possess good overall yields of 20% and 32% for para-IDT(=NCN) 2 and meta-IDT(=NCN) 2 respectively.…”

Poly(DCAQI): Synthesis and characterization of a new redox-active polymer

“…23,24 The transformation of the carbonyl groups of the anthraquinone to N-cyanoimine groups, which possess stronger electron accepting properties, leading to higher reduction potentials of the compound. 25 However, for the application as active material in organic batteries, insolubility of all occurring redox states of the active material is required in the applied electrolytes, which mostly consist of an electrochemically inert salt and an organic solvent. The most promising and straightforward approach is the incorporation of the redox-active units into a polymeric environment, resulting in an insoluble, but swellable electroactive material.…”
