MXene (“maxene”) nanosheets synthesized by liquid-phase exfoliation can be deposited by this mature technology in an emerging strategy for making organic thin-film transistors. For 10 points each:
[10h] Name this process that relies on the inverse piezoelectric effect to programmably dispense picoliters of reagent onto substrate, in either a “continuous” or “drop-on-demand” format.
ANSWER: inkjet printing [accept jetting or 3D jetting or jet printing; prompt on printing; prompt on ink printing]
[10m] The semiconductor in an organic thin film transistor is usually a derivative of this heterocycle like EDOT (“ee dot”). The building block of a common conductive polymer, this molecule is isoelectronic to furan and pyrrole.
ANSWER: thiophene [prompt on C4H4S]
[10e] Inkjet-printed electrodes are a composite of PEDOT (“pee dot”) and the sulfonated polymer of this compound. This common aromatic monomer strengthens acrylonitrile and butadiene in the ABS resin used for 3D printing.
ANSWER: styrene [or polystyrene or PS; or polystyrene sulfonate or PSS; accept PEDOT:PSS]
