These materials have been studied for potential use in OLEDs, including as emissive layer host materials, due to their highly-ordered nature and tunability. For 10 points each:
[10m] Name these highly porous materials that consist of metal ions or clusters coordinated to organic ligands.
ANSWER: metal-organic frameworks [or MOFs]
[10h] One of the most common “struts” used in MOFs is this straight, rigid organic molecule that, with zinc and oxygen, forms MOF-5, which has high volumetric storage density because of partial charges on its surface.
ANSWER: benzene-1,4-di·carboxylic acid [or 1,4-benzene·di·carboxylic acid; or terephthalic acid; or para-phthalic acid; or BDC; or TPA; or PTA; accept any of these answers ending with the suffix “-ate” instead of “-ic acid”]
[10e] MOFs are currently mainly researched for their potential in capturing and storing greenhouse gasses, including this simplest alkane.
ANSWER: methane [or CH4]
