The development of these materials via iodine doping won Heeger, MacDiarmid (“mack-DUR-mid”), and Shirakawa the 2000 Nobel Prize in Chemistry. For 10 points each:
[10h] Name these materials exemplified by PPV and PEDOT, whose most notable property arises from electron movement in their extended conjugated systems.
ANSWER: conducting polymers [or conductive polymers; prompt on polymers]
[10e] Heeger, MacDiarmid, and Shirakawa produced conductive polymers by doping a version of this compound. This simplest alkyne with formula C2H2 is used in welding torches.
ANSWER: acetylene [accept polyacetylene]
[10m] The first conducting polymers were produced in 1862 when Henry Letheby oxidized this compound in sulfuric acid. Iron is used to reduce nitrobenzene into this precursor of indigo dye in the Bechamp reduction.
ANSWER: aniline [or phenylamine; or aminobenzene; or benzenamine]
