Conjugated Polymers Based on Benzo[l,2‐b:4,5‐b′] dithiophene for Organic Electronics

Synthesis of Amphiphilic RuII Heteroleptic Complexes Based on Benzo[1,2‐b:4,5‐b′]dithiophene: Relevance of the Half‐Sandwich Complex Intermediate and Solvent Compatibility

“…[3][4][5] For instance, benzo-fusedd ithiophene (BDT) has emerged as one of this new class of molecules that exhibit remarkable properties. [6][7][8] Their planar,s ymmetric, and rigidly locked, conjugated aromatic structure, usually confert oB DTbased oligo-or polymers inherent advantages compared with other polythiophene-based derivatives. [9] In particular, their aggregation tendency in the solids tate favors ar egulars tacking, thus leading to highly ordered films or p-extended frameworks.…”

“…Moreover,t hey exhibit high-field effectm obility and conductivity,e asy tuneable low band gap and molecular energyl evel control. [10,11] BDT-based materialsw erei nitially developed at thee nd of the 1990s for p-channel organic thin film transistors (TFTs) applications [7] but quickly extended to various areas of research in organic electronics, [6] including organic field-effectt ransistors (OFETs), [12] organic light-emitting diodes( OLEDs), [13] and single-molecule junctions. [14] During the last few years, BDT-based polymers or co-polymers have been widelyu sed for photovoltaic applications in polymer solar cells (PSCs), [15][16][17][18][19][20] tandem or bulk heterojunction (BHJ).…”

“…Sulfur‐containing fused polycyclic heteroaromatic compounds, containing three or more fused rings, have been the focus of interest in this area of research during the past years 3–5. For instance, benzo‐fused dithiophene (BDT) has emerged as one of this new class of molecules that exhibit remarkable properties 6–8. Their planar, symmetric, and rigidly locked, conjugated aromatic structure, usually confer to BDT‐based oligo‐ or polymers inherent advantages compared with other polythiophene‐based derivatives 9.…”
