Packet P: Bonus 12
The binding between these two kinds of compounds is the basis for artificial molecular machines such as molecular tweezers. For 10 points each:
[10m] Name these two kinds of compounds whose non-covalent interactions are studied in a branch of supramolecular chemistry, exemplified by the binding of metal cations to crown ethers.
ANSWER: hosts AND guests [accept host–guest chemistry]
[10e] Host–guest chemistry is analogous to the binding of substrates to these catalytic proteins.
ANSWER: enzymes
[10h] Among the many applications for host–guest chemistry is a room-temperature form of this phenomenon, which occurs when electrons are locked into a slower triplet state.
ANSWER: phosphorescence [prompt on luminescence; reject “fluorescence”]
