Fabrication of Organic Thin-Film Transistors Based on Bis(octylphenyl)chrysenes

Synthesis and Properties of Donor-acceptor-type Polymers Comprising Alkoxy-substituted Bithiophene Units

“…Their low bandgaps result from donor-to-acceptor intramolecular charge transfer (ICT) [4,5]. Furthermore, this low bandgap endows D-A-type polymers with the ability to absorb light in both the visible and near-infrared regions, allowing them to be widely applied to optoelectronic materials used in electrochromic windows [6,7], optical filters and lasers [8], biosensors [9,10], photothermal therapy [11,12], light-emitting diodes [13], thin-film transistors [14], and organic photovoltaics [15][16][17][18][19]. However, although extensive research effort has been committed to controlling the electronic properties of D-A-type polymers by changing the chemical structures of the D and A units, the systematic tuning of these properties has not been well investigated.…”
