A series of donor–acceptor (D–A) type polymers based on a thieno[3,2-b]thiophene isoindigo (TTID) acceptor and five different donors was synthesized to investigate the versatility of the TTID acceptor moiety. To enhance intermolecular interaction

We report donor-acceptor copolymers incorporating electron-donating dimethylsilole and electron-withdrawing diketopyrrolopyrrole (DPP) units. To investigate effects of alkyl chain attached to the DPP unit, 2-decyltetradecyl (24-alkyl) group and 7-dec

The photostability of donor–acceptor (D–A) polymers remains a critical issue despite recent improvements in the power conversion efficiencies (PCEs) of organic photovoltaic (OPV) cells. We report the synthesis of three highly photostable polymers

Here, a novel strategy is reported to develop polymer field effect transistors using ethanol, propanol, and butanol—the most environmentally benign solvent except water—as processing solvents. From such environmentally benign processes, for the f

It is important to develop new donor (D)–acceptor (A) type low band gap polymers for highly stable polymer solar cells (PSCs). Here, we describe the synthesis and photovoltaic properties of two D–A type low band gap polymers. The polymers consist

We report on a new class of microliter-scale solution processes for fabricating highly uniform and large-area transistor arrays with extremely low consumption of semiconducting polymers. These processes are accomplished by applying a vertical phase s

Random copolymerization strategy is introduced to increase the solubility of donor–acceptor copolymers so that they can be processed with environmentally benign, halogen-free solvents. Traditionally, it has been believed that the random copolymer w

An organic-field effect transistor (OFET) based on a newly synthesized organic molecule with an ester end group (ANOAT) was tested in a sensor for the detection of ethanol vapor. The linearly fused acene in ANOAT forms channel layers in the OFET and
