Diketopyrrolopyrrole-based conjugated polymers synthesized by direct arylation polycondensation for anisole-processed high mobility organic thin-film transistors

Abstract

Two conjugated polymers (CPs) Fu-F and Fu-Cl that are soluble in a green solvent anisole were successfully synthesized via direct arylation polycondensation (DArP) using a furan-flanked diketopyrrolopyrrole (DPP) derivative (FDPP-Br)...

Group 16 conjugated polymers based on furan, thiophene, selenophene, and tellurophene

“…So far, DArP has been demonstrated on a variety of heterocyclic aromatic monomers, including thiophenes, [95][96][97][98][99] selenophenes, 100 and furan-flanked building blocks. 101 However, most of the polymer syntheses proceed in a step-growth fashion, which expels some key points of interest in developing polymeric materials, including chain-growth character, MW control, and low Ð. Here, we would like to highlight two strategies that help improve DArP in this regard.…”

Synthetic strategies, molecular engineering and applications of semiconducting polymers based on diarylethylene units in electronic devices

“…For P19 and P20, the introduction of furan enabled these polymers to be dissolved in a green solvent, anisole. 108 Compared to P20, P19 showed a better device performance with an electron mobility of 2.79 cm 2 V À1 s À1 because polymer chains were aligned along the bar-coating direction.…”

Current developments of eco-friendly organic field-effect transistors: from molecular engineering of organic semiconductors to greener device processing

“…Over the past few decades, numerous OSCs that exhibit superior performance based on high mobility have been developed. [39][40][41][42][43][44][45][46][47][48] Most of these semiconductors were prepared by processing them using a solvent containing a halogen atom, especially chlorine, with chloroform and chlorobenzene being prime examples of such a solvent, as shown in Fig. 1.…”
