Theoretical Study Of The Geometric, Electronic Structure And Properties Of Alternating Donor-acceptor Conjugated Oligomers: Carbazole (Cbz)-based 3,4-ethylenedioxythiophene (Edot)

Synthesis and electrochemical polymerization of diketopyrrolopyrrole based donor–acceptor–donor monomers containing 3,6- and 2,7-linked carbazoles

“…[24][25][26] On the other hand, the 2,7functionalized carbazole has become a promising candidate with its more planar and well delocalized π-electron structure for the application of organic photovoltaics. 27 There are also several reports on the optoelectronic properties of 2,7-linked carbazole/DPP polymers. 28,29 The effect of N-substitution on the carbazole unit of a 2,7-linked carbazole-DPP polymer was reported by Y. Li et al 30 J. H. Seo noted that aryl substituents on the 2,7-linked carbazole unit were found to lead to a more planar backbone resulting in a narrower band gap compared to alkyl substituents.…”

Electrochromic Insight on Electro‐Deposited Copolymers of Push‐Pull Conjugated Systems with 3,4‐Ethylenedioxythiophene (EDOT) and Other Conjugated Units

“…[98] Furthermore, theoretical studies propose that not only the acceptor strength but also the stable geometry affects the electronic properties of push-pull type CPs. [99][100][101] Lastly, it must be highlighted that electrochemical technique is an effective, fast, and easy way of preparing a copolymer as a thin film. Moreover, electrodeposition allows adjusting the feed ratio and comparing the electrochromic properties of resulting copolymers according to each.…”

“…can create noncovalent conformational locks which planarize and rigidify the conjugated backbone and alter the band gap [98] . Furthermore, theoretical studies propose that not only the acceptor strength but also the stable geometry affects the electronic properties of push‐pull type CPs [99–101] …”

Prediction and Simulation of electrical and optical characteristics of an OLED based on P3BEdotBT3A organic material

“…rc = e 2 /(4πr0kBT) (16) r is the dielectric constant of the organic material, 0 is the dielectric permittivity of vacuum, and kB is the Boltzmann constant. The Langevin recombination rate coefficient is given by [29,31]:…”

“…And since that time researchers have started to develop new organic semiconductor materials and improve their properties [14]. They make it possible in particular to synthesize materials with highperformance optoelectronic properties (mechanical characteristics and optical properties) [15][16][17][18] for welltargeted applications.…”
