Furan-containing conjugated polymers for organic solar cells

High‐Performance Ternary Polymer Solar Cells Enabled by a New Narrow Bandgap Nonfullerene Small Molecule Acceptor with a Higher LUMO Level

“…In thin film, the absorption was broadened and the peak was redshifted to 810 nm compared to solution state, which represents a stronger intermolecular interaction in solid state. [ 76,77 ] The absorption onset was up to 950 nm, from which the optical bandgap was estimated to be ≈1.31 eV, which is close to the optical bandgap of the IEICO‐4F (1.29 eV). In comparison to the DMOT on IDTS‐4F, the larger π‐spacer TT on TT‐S‐4F extended the conjugated system, so obtaining a more redshifted absorption (810 nm vs 765 nm).…”

Catalyst‐Free Synthesis of O‐Heteroacenes by Ladderization of Fluorinated Oligophenylenes

“…The incorporation of heteroatoms into the carbon skeleton is an excellent tool to adjust and improve the electronic properties of the compounds [5, 6] . In contrast to nitrogen‐ and sulfur‐analogues, [7–9] oxygen heterocycles, for example, containing furan's moiety, have drawn much less attention and became an object of interest only recently [10–19] …”

Exploring the Electronic Properties of Extended Benzofuran‐Cyanovinyl Derivatives Obtained from Lignocellulosic and Carbohydrate Platforms Raw Materials

“…[11,12,13,14] Over the last decade, works about furan-based conjugated derivatives brought out relevant benefits of the furan cycle for the development of semi-conducting materials for optoelectronic devices. [15,16,17,18] The insertion of low aromaticity cycle such as furan into a conjugated chain allows to increase the rigidity and the planarity of the structure and thus to enhance the electronic delocalization along the conjugated systems. [18,19] Benzofuran represents also a privileged heterocyclic framework with extensive applications in medicinal chemistry and material sciences.…”

“…On the other hand, many works are also devoted to the access of furaldehyde derivatives such as 5‐hydroxymethylfurfural (HMF) from biomass derived carbohydrates for the development of new generation of biofuels or as renewable raw materials for chemistry in pharmaceutical or materials chemistry [11,12,13,14] . Over the last decade, works about furan‐based conjugated derivatives brought out relevant benefits of the furan cycle for the development of semi‐conducting materials for optoelectronic devices [15,16,17,18] .
