Question

Tang and Van Sylke constructed the first electroluminescent device described by this adjective, which relied on a 600-angstrom layer of Alq3 to function. Charge injection occurs between the HOMO hole and LUMO electron injection layers in LEDs described by this word. “Covalent” structures described by this adjective can be synthesized by boron- or triazine- (“TRY-uh-zeen”) based condensations (10[1])as developed by Omar Yaghi. An aluminum (10[1]-5[1])oxide layer supposedly allowed Jan (10[1])Hendrik Schön (10[1])to create (-5[1])transistors (-5[1])described by this adjective (-5[1])before his results were revealed to be fabricated. “Struts” described by this adjective link metallic clusters to improve the porosity (-5[1])of “metal frameworks” (10[1])described by this adjective. (10[1]-5[1])For 10 points, name this adjective that describes the (10[1])branch of chemistry (10[2])that studies carbon-containing (10[2])compounds. (10[1])■END■ (10[8]0[2])

ANSWER: organic [accept organic light emitting diodes or organic LEDs; accept covalent organic frameworks or metal–organic frameworks; accept organic transistors]
