Issue Date: | 2024 | Publisher: | WILEY-V C H VERLAG GMBH | Source: | ADVANCED FUNCTIONAL MATERIALS, (1) , p. 89 -93 | Status: | Early view | Abstract: | This study reports on the first all-printed vertically stacked organic electrochemical transistors (OECTs) operating in accumulation mode; the devices, relying on poly([4,4 '-bis(2-(2-(2-methoxyethoxy)ethoxy)ethoxy)-2,2 '-bithiophen-5,5 '-diyl]-alt-[thieno[3,2-b]thiophene-2,5-diyl]) (pgBTTT) as the active channel material, are fabricated via a combination of screen and inkjet printing technologies. The resulting OECTs (W/L approximate to 5) demonstrate good switching performance; g(m, norm) approximate to 13 mS cm(-1), mu C* approximate to 21 F cm(-1) V-1 s(-1), ON-OFF ratio > 10(4) and good cycling stability upon continuous operation for 2 h. The inkjet printing process of pgBTTT is established by first solubilizing the polymer in dihydrolevoglucosenone (Cyrene), a non-toxic, cellulose-derived, and biodegradable solvent. The resulting ink formulations exhibit good jettability, thereby providing reproducible and stable p-type accumulation mode all-printed OECTs with high performance. Besides the environmental and safety benefits of this solvent, this study also demonstrates the assessment of how the solvent affects the performance of spin-coated OECTs, which justifies the choice of Cyrene as an alternative to commonly used harmful solvents such as chloroform, also from a device perspective. Hence, this approach shows a new possibility of obtaining more sustainable printed electronic devices, which will eventually result in all-printed OECT-based logic circuits operating in complementary mode. | Notes: | Ersman, PA (corresponding author), Smart Hardware Printed Bio & Organ Elect, RISE Res Inst Sweden, Digital Syst, S-60233 Norrkoping, Sweden. peter.andersson.ersman@ri.se |
